Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid
Pull HID updates from Jiri Kosina: "This time it's surprisingly quiet (probably due to the christmas break): - Logitech HID++ protocol improvements from Mazin Rezk, Pedro Vanzella and Adrian Freund - support for hidraw uniq ioctl from Marcel Holtmann" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/hid/hid: HID: logitech-hidpp: avoid duplicate error handling code in 'hidpp_probe()' hid-logitech-hidpp: read battery voltage from newer devices HID: logitech: Add MX Master 3 Mouse HID: logitech-hidpp: Support WirelessDeviceStatus connect events HID: logitech-hidpp: Support translations from short to long reports HID: hidraw: add support uniq ioctl
