Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID subsystem updates from Jiri Kosina: "Apart from various driver updates and added support for a number of new devices (mostly multitouch ones, but not limited to), there is one change that is worth pointing out explicitly: creation of HID device groups and proper autoloading of hid-multitouch, implemented by Henrik Rydberg." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (50 commits) HID: wacom: fix build breakage without CONFIG_LEDS_CLASS HID: waltop: Extend barrel button fix HID: hyperv: Set the hid drvdata correctly HID: wacom: Unify speed setting HID: wacom: Add speed setting for Intuos4 WL HID: wacom: Move Graphire raport header check. HID: uclogic: Add support for UC-Logic TWHL850 HID: explain the signed/unsigned handling in hid_add_field() HID: handle logical min/max signedness properly in parser HID: logitech: read all 32 bits of report type bitfield HID: wacom: Add LED selector control for Wacom Intuos4 WL HID: hid-multitouch: fix wrong protocol detection HID: wiimote: Fix IR data parser HID: wacom: Add tilt reporting for Intuos4 WL HID: multitouch: MT interface matching for Baanto HID: hid-multitouch: Only match MT interfaces HID: Create a common generic driver HID: hid-multitouch: Switch to device groups HID: Create a generic device group HID: Allow bus wildcard matching ...
