It used to grab an extra reference to struct file rather than
just transferring to caller the one it had removed from descriptor
table. New variant doesn't, and callers need to be adjusted.

When a machine sports more than one SP804 timer instance, we only bring
up the first one, since multiple timers of the same kind are not useful
to Linux. As this is intentional behaviour, we should not return an
error message, as we do today:
===============
[ 0.000800] Failed to initialize '/bus@8000000/motherboard-bus@8000000/iofpga-bus@300000000/timer@120000': -22
===============
Replace the -EINVAL return with a debug message and return 0 instead.
Also we do not reach the init function anymore if the DT node is
disabled (as this is now handled by OF_DECLARE), so remove the explicit
check for that case.
This fixes a long standing bogus error when booting ARM's fastmodels.

Some implementations of the SBI time extension depend on hart-local
state (for example, CSRs) that are lost or hardware that is powered
down when a CPU is suspended. To be safe, the clockevents driver
cannot assume that timer IRQs will be received during CPU suspend.

The ql_dm_tgt_ex_pct parameter was introduced in commit ead038556f64
("qla2xxx: Add Dual mode support in the driver"). Then the use of this
parameter was dropped in commit 99e1b683c4be ("scsi: qla2xxx: Add
ql2xiniexchg parameter").
Thus, remove ql_dm_tgt_ex_pct since it is no longer used.

similar. They free a 'req' and a 'rsp' parameter respectively. The last

Make sure to always free a scsi disk zone information, even for regular
disks. This ensures that there is no memory leak, even in the case of a
zoned disk changing type to a regular disk (e.g. with a reformat using the
FORMAT WITH PRESET command or other vendor proprietary command).
To do this, rename sd_zbc_clear_zone_info() to sd_zbc_free_zone_info() and
remove sd_zbc_release_disk(). A call to sd_zbc_free_zone_info() is added to
sd_zbc_read_zones() for drives for which sd_is_zoned() returns
false. Furthermore, sd_zbc_free_zone_info() code make s sure that the sdkp
rev_mutex is never used while not being initialized by gating the cleanup
code with a a check on the zone_wp_update_buf field as it is never NULL
when rev_mutex has been initialized.

If sd_probe() sees an early error before sdkp->device is initialized,
sd_zbc_release_disk() is called. This causes a NULL pointer dereference
when sd_is_zoned() is called inside that function. Avoid this by removing
the call to sd_zbc_release_disk() in sd_probe() error path.
This change is safe and does not result in zone information memory leakage
because the zone information for a zoned disk is allocated only when
sd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set,
resulting in sd_disk_release() being called when needed to cleanup a disk
zone information using sd_zbc_release_disk().

During driver unload, mrioc->bsg_device reference count becomes
negative. Also, as reported in [1], the driver's bsg_device model had few
more bugs. Fix all these up.

When myrb_probe() fails the callback might not be set, so we need to
validate the 'disable_intr' callback in myrb_cleanup() to not cause a null
pointer exception. And while at it do not call myrb_cleanup() if we cannot
enable the PCI device at all.

Split the drivers/scsi/ufs directory into 'core' and 'host' directories
under the drivers/ufs/ directory. Move shared header files into the
include/ufs/ directory. This separation makes it clear which header files
UFS drivers are allowed to include (include/ufs/*.h) and which header files
UFS drivers are not allowed to include (drivers/ufs/core/*.h).
Update the MAINTAINERS file. Add myself as a UFS reviewer.

Add nvme_fc_io_getuuid() to the nvme-fc transport. The routine is invoked
by the FC LLDD on a per-I/O request basis. The routine translates from the
FC-specific request structure to the bio and the cgroup structure in order
to obtain the FC appid stored in the cgroup structure. If a value is not
set or a bio is not found, a NULL appid (aka uuid) will be returned to the
LLDD.

Pull hardware timestamping subsystem from Thierry Reding:
"This contains the new HTE (hardware timestamping engine) subsystem
that has been in the works for a couple of months now.
The infrastructure provided allows for drivers to register as hardware
timestamp providers, while consumers will be able to request events
that they are interested in (such as GPIOs and IRQs) to be timestamped
by the hardware providers.
Note that this currently supports only one provider, but there seems
to be enough interest in this functionality and we expect to see more
drivers added once this is merged"
[ Linus Walleij mentions the Intel PMC in the Elkhart and Tiger Lake
platforms as another future timestamp provider ]

del_timer() does not wait until the timer handler finishing.
This means that the timer handler may still be running after
the driver's remove function has finished, which would result
in a use-after-free.
Fix it by calling del_timer_sync(), which makes sure the timer
handler has finished.

This patch adds new clock type for the GPIO controller which can
timestamp gpio lines in using hardware means. To expose such
functionalities to the userspace, code has been added where
during line create or set config API calls, it checks for new
clock type and if requested, calls HTE API. During line change
event, the HTE subsystem pushes timestamp data to userspace
through gpiolib-cdev.
