platform/x86: thinkpad_acpi: Remove always false 'value < 0' statement

2020-05-05T12:33:24Z

Since 'value' is declared as unsigned long, the following statement is always false. value < 0 So let's remove it. Reported-by: Hulk Robot Signed-off-by: Xiongfeng Wang Signed-off-by: Andy Shevchenko

platform/x86: intel_pmc_core: avoid unused-function warnings

2020-05-05T12:33:24Z

When both CONFIG_DEBUG_FS and CONFIG_PM_SLEEP are disabled, the functions that got moved out of the #ifdef section now cause a warning: drivers/platform/x86/intel_pmc_core.c:654:13: error: 'pmc_core_lpm_display' defined but not used [-Werror=unused-function] 654 | static void pmc_core_lpm_display(struct pmc_dev *pmcdev, struct device *dev, | ^~~~~~~~~~~~~~~~~~~~ drivers/platform/x86/intel_pmc_core.c:617:13: error: 'pmc_core_slps0_display' defined but not used [-Werror=unused-function] 617 | static void pmc_core_slps0_display(struct pmc_dev *pmcdev, struct device *dev, | ^~~~~~~~~~~~~~~~~~~~~~ Rather than add even more #ifdefs here, remove them entirely and let the compiler work it out, it can actually get rid of all the debugfs calls without problems as long as the struct member is there. The two PM functions just need a __maybe_unused annotations to avoid another warning instead of the #ifdef.

platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA

2020-05-05T12:32:51Z

asus-nb-wmi does not add any extra functionality on these Asus Transformer books. They have detachable keyboards, so the hotkeys are send through a HID device (and handled by the hid-asus driver) and also the rfkill functionality is not used on these devices. Besides not adding any extra functionality, initializing the WMI interface on these devices actually has a negative side-effect. For some reason the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED, high and there is no (WMI or other) interface to drive this low again causing the LED to be permanently on, even during suspend. This commit adds a blacklist of DMI system_ids on which not to load the asus-nb-wmi and adds these Transformer books to this list. This fixes the webcam LED being permanently on under Linux.

platform/x86: intel_pmc_core: Change Jasper Lake S0ix debug reg map back to ICL

2020-05-05T12:32:41Z

Jasper Lake uses Icelake PCH IPs and the S0ix debug interfaces are same as Icelake. It uses SLP_S0_DBG register latch/read interface from Icelake generation. It doesn't use Tiger Lake LPM debug registers. Change the Jasper Lake S0ix debug interface to use the ICL reg map.
