HID: Merge branch 'master' into for-3.10/hid-driver-transport-cleanups
Sync with Linus' tree. This is necessary to resolve build conflict caused by dcd9006b1b053c7b ("HID: logitech-dj: do not directly call hid_output_raw_report() during probe") which issues direct call to usbhid_submit_report(), but that is gone in this branch and hid_hw_request() has to be used instead.
