platform/x86: peaq-wmi: Add DMI check before binding to the WMI interface

2017-11-21T09:24:35+00:00

commit 3b95206110a2c13076c3a7fa8ddeae36c2dbcf42 upstream. It seems that the WMI GUID used by the PEAQ 2-in-1 WMI hotkeys is not as unique as a GUID should be and is used on some other devices too. This is causing spurious key-press reports on these other devices. This commits adds a DMI check to the PEAQ 2-in-1 WMI hotkeys driver to ensure that it is actually running on a PEAQ 2-in-1, fixing the spurious key-presses on these other devices.

platform/x86: fujitsu-laptop: Don't oops when FUJ02E3 is not presnt

2017-10-05T07:47:35+00:00

commit ce7c47d60bda6c7f09ccf16e978d971c8fa16ff0 upstream. My Fujitsu-Siemens Lifebook S6120 doesn't have the FUJ02E3 device, but it does have FUJ02B1. That means we do register the backlight device (and it even seems to work), but the code will oops as soon as we try to set the backlight brightness because it's trying to call call_fext_func() with a NULL device. Let's just skip those function calls when the FUJ02E3 device is not present.

platform/x86: intel-vbtn: match power button on press rather than release

2017-08-05T21:37:19+00:00

This fixes a problem where the system gets stuck in a loop unable to wakeup via power button in s2idle. The problem happens because: - press power button: - system emits 0xc0 (power press), event ignored - system emits 0xc1 (power release), event processed, emited as KEY_POWER - set wakeup_mode to true - system goes to s2idle - press power button - system emits 0xc0 (power press), wakeup_mode is true, system wakes - system emits 0xc1 (power release), event processed, emited as KEY_POWER - system goes to s2idle again To avoid this situation, process the presses (which matches what intel-hid does too).

platform/x86: dell-wmi: Fix driver interface version query

2017-08-01T22:41:43+00:00

When I converted dell-wmi to the new bus infrastructure, I left the call to dell_wmi_check_descriptor_buffer() in dell_wmi_init(). This could cause two problems: - An error message when loading the driver on a system without dell-wmi. We'd try to read the event descriptor even if the WMI GUID wasn't there. - A possible race if dell-wmi was loaded manually before wmi was fully initialized. Fix it by moving the call to the probe function where it belongs.

platform/x86: peaq-wmi: select INPUT_POLLDEV

2017-07-20T23:57:51+00:00

The new driver fails to build without INPUT_POLLDEV drivers/platform/x86/peaq-wmi.o: In function `peaq_wmi_exit': peaq-wmi.c:(.exit.text+0x1c): undefined reference to `input_unregister_polled_device' drivers/platform/x86/peaq-wmi.o: In function `peaq_wmi_init': peaq-wmi.c:(.init.text+0x23): undefined reference to `input_allocate_polled_device' peaq-wmi.c:(.init.text+0x18e): undefined reference to `input_register_polled_device' For some reason, all other drivers that need this use 'select' here rather than 'depends on', so I'm doing the same.
