2018-01-16platform/x86: dell-laptop: Filter out spurious keyboard backlight change eventsHans de Goede
On some Dell XPS models WMI events of type 0x0000 reporting a keycode of 0xe00c get reported when the brightness of the LCD panel changes. This leads to us reporting false-positive kbd_led change events to userspace which in turn leads to the kbd backlight OSD showing when it should not. We already read the current keyboard backlight brightness value when reporting events because the led_classdev_notify_brightness_hw_changed API requires this. Compare this value to the last known value and filter out duplicate events, fixing this. Note the fixed issue is esp. a problem on XPS models with an ambient light sensor and automatic brightness adjustments turned on, this causes the kbd backlight OSD to show all the time there.

2018-01-15platform/x86: have ACPI_CMPC use depends instead of select for INPUTRandy Dunlap
Drivers should not 'select' a subsystem. Instead they should depend on it. If the subsystem is disabled, the user probably did that for a purpose and one driver shouldn't be changing that. This also makes all platform/x86/ drivers consistent w.r.t depending on INPUT instead of selecting it.

2018-01-08platform/x86: wmi: Call acpi_wmi_init() laterRafael J. Wysocki
Calling acpi_wmi_init() at the subsys_initcall() level causes ordering issues to appear on some systems and they are difficult to reproduce, because there is no guaranteed ordering between subsys_initcall() calls, so they may occur in different orders on different systems. In particular, commit 86d9f48534e8 (mm/slab: fix kmemcg cache creation delayed issue) exposed one of these issues where genl_init() and acpi_wmi_init() are both called at the same initcall level, but the former must run before the latter so as to avoid a NULL pointer dereference. For this reason, move the acpi_wmi_init() invocation to the initcall_sync level which should still be early enough for things to work correctly in the WMI land.

The new notify_handler logic determining if autorelease should be used or not is a bit awkward, and can result in more than one call to sparse_keymap_report_event for the same event (scancode). The nesting and long lines also made it difficult to read.
