Pull NVDIMM and DAX fixes from Dan Williams:
"A recently discovered one-line fix for devdax that further addresses a
v5.5 regression, and (a bit embarrassing) a small batch of fixes that
have been sitting in my fixes tree for weeks.
The older fixes have soaked in linux-next during that time and address
an fsdax infinite loop and some other minor fixups.
- Fix a infinite loop bug in fsdax
- Fix memory-type detection for devdax (EINJ regression)
- Small cleanups"

The "hmem" platform-devices that are created to represent the
platform-advertised "Soft Reserved" memory ranges end up inserting a
resource that causes the iomem_resource tree to look like this:
340000000-43fffffff : hmem.0
340000000-43fffffff : Soft Reserved
340000000-43fffffff : dax0.0
This is because insert_resource() reparents ranges when they completely
intersect an existing range.
This matters because code that uses region_intersects() to scan for a
given IORES_DESC will only check that top-level 'hmem.0' resource and
not the 'Soft Reserved' descendant.
So, to support EINJ (via einj_error_inject()) to inject errors into
memory hosted by a dax-device, be sure to describe the memory as
IORES_DESC_SOFT_RESERVED. This is a follow-on to:
commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP")
...that fixed EINJ support for "Soft Reserved" ranges in the first
instance.

A couple years back we went through the kernel an automatically
converted size calculations to use struct_size() instead. The
struct_size() calculation is protected against integer overflows.
However it does not make sense to use the result from struct_size()
for additional math operations as that would negate any safeness.

The i2c-mlxbf.c driver is currently broken because there is a bug
in the calculation of the frequency. core_f, core_r and core_od
are components read from hardware registers and are used to
compute the frequency used to compute different timing parameters.
The shifting mechanism used to get core_f, core_r and core_od is
wrong. Use FIELD_GET to mask and shift the bitfields properly.

Correct the base address used during io write.
This bug had no impact over the overall functionality of the read and write
transactions. MLXBF_I2C_CAUSE_OR_CLEAR=0x18 so writing to (smbus->io + 0x18)
instead of (mst_cause->ioi + 0x18) actually writes to the sc_low_timeout
register which just sets the timeout value before a read/write aborts.

It is not necessary to go through the process of validation, linking of
queues to mdev and vice versa and filtering the APQNs assigned to the
matrix mdev to build an AP configuration for a guest if an adapter or
domain being assigned is already assigned to the matrix mdev. Likewise, it
is not necessary to proceed through the process the unassignment of an
adapter, domain or control domain if it is not assigned to the matrix mdev.
Since it is not necessary to process assignment of a resource already
assigned or process unassignment of a resource that is been assigned,
this patch will bypass all assignment/unassignment operations for an
adapter, domain or control domain under these circumstances.
Not only is assignment of a duplicate adapter or domain unnecessary, it
will also cause a hang situation when removing the matrix mdev to which it is
assigned. The reason is because the same vfio_ap_queue objects with an
APQN containing the APID of the adapter or APQI of the domain being
assigned will get added multiple times to the hashtable that holds them.
This results in the pprev and next pointers of the hlist_node (mdev_qnode
field in the vfio_ap_queue object) pointing to the queue object itself
resulting in an interminable loop when the mdev is removed and the queue
table is iterated to reset the queues.

IRQ trigger configuration is skipped if it has already been set before;
however, the IRQ line still needs to be OR'd to irq_enabled because
irq_enabled is reset for every events_configure call. This patch moves
the irq_enabled OR operation update to before the irq_trigger check so
that IRQ line enablement is not skipped.

There is an error check following the allocation of flash_buf that returns
without freeing flash_buf. It makes more sense to do the error check
before the allocation and the reordering eliminates the memory leak.

Reset support for SATA PHY is somehow broken and after calling it, kernel
is not able to detect and initialize SATA disk Samsung SSD 850 EMT0 [1].
Reset support was introduced in commit 934337080c6c ("phy: marvell:
phy-mvebu-a3700-comphy: Add native kernel implementation") as part of
complete rewrite of this driver. v1 patch series of that commit [2] did
not contain reset support and was tested that is working fine with
Ethernet, SATA and USB PHYs without issues too.
So for now remove broken reset support and change implementation of
power_off callback to power off all functions on specified lane (and not
only selected function) because during startup kernel does not know which
function was selected and configured by bootloader. Same logic was used
also in v1 patch series of that commit.
This change fixes issues with initialization of SATA disk Samsung SSD 850
and disk is working again, like before mentioned commit.
Once problem with PHY reset callback is solved its functionality could be
re-introduced. But for now it is unknown why it does not work.

Pull tty/serial driver fixes from Greg KH:
"Here are some small, and late, serial driver fixes for 6.0-rc7 to
resolve some reported problems.
Included in here are:
- tegra icount accounting fixes, including a framework function that
other drivers will be converted over to using in 6.1-rc1.
- fsl_lpuart reset bugfix
- 8250 omap 485 bugfix
- sifive serial clock bugfix
The last three patches have not shown up in linux-next due to them
being added to my tree only 2 days ago, but they are tiny and
self-contained and the developers say they resolve issues that they
have with 6.0-rc. The other three have been in linux-next for a while
with no reported issues"

When the PWM driver was changed to disable clocks if no PWMs are enabled,
it ended up also disabling the shared parent with the UART, since the
UART doesn't do any clock enablement on its own.
To avoid these surprises, switch to clk_get_enabled().

8250_omap uses em485, fill in rs485_supported accordingly. This makes
RS485 work with 8250_omap again, which was broken with the introduction

Since commit bd5305dcabbc ("tty: serial: fsl_lpuart: do software reset
for imx7ulp and imx8qxp"), certain i.MX UARTs are reset after they've
already been registered. Register state may thus be clobbered after
user space has begun to open and access the UART.
Avoid by performing the reset prior to registration.

Fix Oops in dasd_alias_get_start_dev() function caused by the pavgroup
pointer being NULL.
The pavgroup pointer is checked on the entrance of the function but
without the lcu->lock being held. Therefore there is a race window
between dasd_alias_get_start_dev() and _lcu_update() which sets
pavgroup to NULL with the lcu->lock held.
Fix by checking the pavgroup pointer with lcu->lock held.

CMN-600 uses bits [27:0] for child node address offset while bits [30:28]
are required to be zero.
For CMN-650, the child node address offset field has been increased
to include bits [29:0] while leaving only bit 30 set to zero.
Let's include the missing two bits and assume older implementations
comply with the spec and set bits [29:28] to 0.

Pull driver core fixes from Greg KH:
"Here are two tiny driver core fixes for 6.0-rc7 that resolve some
oft-reported problems.
The first is a revert of the "fw_devlink.strict=1" default option that
we keep trying to enable, but we keep finding platforms that this just
breaks everything on. So again, we need it reverted and hopefully it
can be worked on in future releases.
The second is a sysfs file-size bugfix that resolves an issue that
many people are starting to hit as the fix it is fixing also was
backported to stable kernels. The util-linux developers are starting
to get bugreports about sysfs files that contain no data because of
this problem, and this fix which has been in linux-next in the
bitfield tree for a long time, resolves it. I'm submitting it here as
it needs to be merged for 6.0-final, not for 6.1-rc1.
Both of these have been in linux-next with no reported issues, only
reports were that these fixed problems"

Commit d725d20e81c2 ("media: flexcop-usb: sanity checking of endpoint

isochronous endpoint but instead broke the driver by checking the wrong

Make sure to check the right endpoint descriptor.

On some DWC3 controllers (e.g. Rockchip SoCs), the DWC3 core
doesn't support 64-bit DMA address width. In this case, this
driver should use the default 32-bit mask. Otherwise, the DWC3
controller will break if it runs on above 4GB physical memory
environment.
This patch reads the DWC_USB3_AWIDTH bits of GHWPARAMS0 which
used for the DMA address width, and only configure 64-bit DMA
mask if the DWC_USB3_AWIDTH is 64.

The Kconfig symbol depended on MMU but was dropped by the commit
acad3fe650a5 ("drm/hisilicon: Removed the dependency on the mmu")
because it already had as a dependency ARM64 that already selects MMU.
But later, commit a0f25a6bb319 ("drm/hisilicon/hibmc: Allow to be built
if COMPILE_TEST is enabled") allowed the driver to be built for non-ARM64
when COMPILE_TEST is set but that could lead to unmet direct dependencies
and linking errors.
Prevent a kconfig warning when MMU is not enabled by making
DRM_HISI_HIBMC depend on MMU.

G200ER does not seem to support 24 bpp, so force the console to
use 32 bpp. The problem got introduced when commit 73f54d5d9682
("drm/mgag200: Remove special case for G200SE with <2 MiB") changed
the preferred color depth from 32 bit to 24 bit.
A setting of 24 is the correct color depth, but G200ER doesn't seem
to be able to use the respective RGB888 color format. Using 24-bit
color with forced 32 bpp works around the problem.
