Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID fixes from Jiri Kosina: - fix for how scaling linearization is computed in wiimote driver, by Cyan Ogilvie - endless retry loop fix in generic USB HID core reset-resume handling, by Alan Stern - two functional fixes affecting particular devices, and oops fix for wacom driver, by Jason Gerecke - multitouch slot numbering fix from Gabriele Mazzotta - a couple more small fixes on top * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: HID: wacom: Support switching from vendor-defined device mode on G9 and G11 HID: wacom: Initialize hid_data.inputmode to -1 HID: microsoft: add support for 3 more devices HID: multitouch: Synchronize MT frame on reset_resume HID: wacom: fix Bamboo ONE oops HID: lenovo: Don't use stack variables for DMA buffers HID: usbhid: fix inconsistent reset/resume/reset-resume behavior HID: wiimote: Fix wiimote mp scale linearization
