Merge tag 'platform-drivers-x86-v4.3-2' of git://git.infradead.org/users/dvhart/linux-platform-drivers-x86
Pull x86 platform driver fixes from Darren Hart:
"Fix an issue introduced by the previous major toshiba rework. Add a
quirk. Workaround a few platform specific firmware items. One
cleanup to wmi I inadvertently dropped from a previous pull request.
Details:
hp-wmi:
- limit hotkey enable
toshiba_acpi:
- Fix hotkeys registration on some toshiba models
- Fix USB Sleep and Music always disabled
wmi:
- Remove private %pUL implementation
asus-nb-wmi:
- Add wapf=4 quirk for X456UA/X456UF"
