Merge tag 'platform-drivers-x86-v4.6-2' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull x86 platform driver fixes from Darren Hart:
"An S4 fix for intel-hid, new platform 'quirk' for hp_accel, a fix for
broader support of ACPI resources for the Intel P-unit, and a few
uninitialized variable fixes.
intel p-unit:
- decouple telemetry driver from the optional IPC resources
thinkpad_acpi:
- Silence an uninitialized variable warning
intel_telemetry_pltdrv:
- Silence an uninitialized variable warning
hp_accel:
- Silence an uninitialized variable warning
- Add support for HP ProBook 440 G3
intel-hid:
- add a workaround to ignore an event after waking up from S4"
