Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer updates from Dmitry Torokhov: "2nd round of updates for the input subsystem. With it input core no longer limits number of character devices per event handler (such as evdev) to 32, but switches to dynamic minors once legacy range is exhausted. This should get multi-seat installations that currently run our of event devices very quickly. You will also get an update for Wacom driver and a couple of driver fixes." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: extend the number of event (and other) devices Input: mousedev - mark mousedev interfaces as non-seekable Input: mousedev - rename mixdev_open to opened_by_mixdev Input: mousedev - reformat structure initializers Input: mousedev - factor out psaux code to reduce #ifdefery Input: samsung-keypad - add clk_prepare and clk_unprepare Input: atmel_mxt_ts - simplify mxt_dump_message Input: wacom - clean up wacom_query_tablet_data Input: wacom - introduce wacom_fix_phy_from_hid Input: wacom - allow any multi-input Intuos device to set prox Input: wacom - report correct touch contact size for I5/Bamboo
