* platform/x86: sony-laptop: replace snprintf in show functions with sysfs_emitYe Guojin2021-10-221-28/+18
| | | | | | | | | | | | | | coccicheck complains about the use of snprintf() in sysfs show functions: WARNING use scnprintf or sprintf Use sysfs_emit instead of scnprintf or sprintf makes more sense.

* platform/x86: sony-laptop: SNC calls should handle BUFFER typesMattia Dongili2020-05-121-30/+23
| | | | | | | | | | | | | | | | | | After commit 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer objects for ASL create_field() operator") ACPICA creates buffers even when new fields are small enough to fit into an integer. Many SNC calls counted on the old behaviour. Since sony-laptop already handles the INTEGER/BUFFER case in sony_nc_buffer_call, switch sony_nc_int_call to use its more generic function instead.

* vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds2018-02-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

The behaviour of the driver changes whereby previously when passed 1 it tried to turn on backlight immediately now it does nothing. This is however a bug fix since (a) it makes little sense to turn on the backlight when control is automatic and (b) this behaviour is consistent with what the windows driver does.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

|/ | | | | | | | | | | | | | | | | | | | | | | Some BIOS versions/Vaio models apparently ship with two nearly identical functions to handle backlight related controls. The only difference seems to be: If (LEqual (BUF1, 0x40)) { Store (0x40, P80H) Store (BUF2, Local0) - And (Local0, One, Local0) + And (Local0, 0x03, Local0) Store (Local0, ^^H_EC.KLPC) } Avoid erroring out on initialization and messing things up on cleanup for now since we never call into these methods with anything different than 1 or 0.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | acpi_has_method() is a new ACPI API introduced to check the existence of an ACPI control method. It can be used to replace acpi_get_handle() in the case that 1. the calling function doesn't need the ACPI handle of the control method. and 2. the calling function doesn't care the reason why the method is unavailable.
