| * | platform/x86: fujitsu-laptop: Unify local variable namingMichał Kępień2018-02-241-44/+41Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Different functions in the module use varying names (error, result, status) for a local variable storing the return value of a function call that has to be checked for errors. Use a common name (ret) for all these local variables to improve code consistency. Merge integer variable declarations in acpi_fujitsu_laptop_add() into one line.

| * | platform/x86: topstar-laptop: add Topstar U931/RVP7 WLAN LED workaroundGuillaume Douézan-Grard2018-02-232-0/+110
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Topstar U931 laptops provide a LED synced with the WLAN adapter hard-blocking state. Unfortunately, some models seem to be defective, making impossible to hard-block the adapter with the WLAN switch and thus the LED is useless. An ACPI method is available to programmatically control this switch and it indirectly allows to control the LED. This commit registers the LED within the corresponding subsystem, making possible for instance to use an rfkill-based trigger to synchronize the LED with the device state. This workaround is enabled automatically for Topstar U931/RVP7 laptops based on a DMI check.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On systems supporting HWP (Hardware P-States) mode, we expected to enumerate core priority via ACPI-CPPC tables. Unfortunately deployment of TURBO 3.0 didn't use this method to show core priority. So users are not able to utilize this feature in HWP mode. So remove the loading restriction of this driver for HWP enabled systems. Even if there are some systems, which are providing the core priority via ACPI CPPC, this shouldn't cause any conflict as the source of priority definition is same.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the DELL_SMBIOS_SMM backend is enabled, the DELL_SMBIOS symbol depends on DELL_DCDBAS, and we must avoid the situation where DELL_SMBIOS=y and DCDBAS=m. Adding the conditional dependency to DELL_SMBIOS such as: depends !DELL_SMBIOS_SMM || (DCDBAS || DCDBAS=n) results in the Kconfig tooling complaining about a circular dependency, although it appears to work in practice. Avoid the errors by simplifying the dependency and forcing DELL_SMBIOS to be <= DCDBAS if DCDBAS is enabled (thanks to Greg KH for the suggestion).

Avoid this impacting the default build size, by making them dependent on DELL_SMBIOS, so they only appear when DELL_SMBIOS is manually selected, or by DELL_LAPTOP or DELL_WMI. While DELL_SMBIOS does have a prompt, it does not have any dependencies. Keeping DELL_SMBIOS visible, despite being "select"ed by DELL_LAPTOP and DELL_WMI, is a deliberate choice to provide context for the WMI and SMM backends, which would otherwise appear to float without context within the menu.

* vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds2018-02-113-6/+6
| | | | | | | | | | | | | | | | | | | | | | | 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>
