Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid
Pull HID fixes from Jiri Kosina:
- hid.git is moving towards group maintainership (where group is myself
and Benjamin Tissoires), therefore this pull request updates
MAINTAINERS accordingly
- fix for hid-asus config dependency from Arnd Bergmann
- two device-specific quirks for i2c-hid from Julian Sax and Kai-Heng
Feng
- other few small assorted fixes
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid:
HID: fix up .raw_event() documentation
HID: asus: fix build warning wiht CONFIG_ASUS_WMI disabled
HID: i2c-hid: add Direkt-Tek DTLAPY133-1 to descriptor override
HID: moving to group maintainership model
HID: alps: allow incoming reports when only the trackstick is opened
Revert "HID: add NOGET quirk for Eaton Ellipse MAX UPS"
HID: i2c-hid: Add a small delay after sleep command for Raydium touchpanel
HID: hiddev: fix potential Spectre v1
