This commit adds support for the Guitar Hero Live PS3 and Wii U dongles. These dongles require a "magic" USB control message [1] to be sent approximately every 10 seconds otherwise the dongle will not report events where the strumbar is hit while a fret is being held. Also, inspired by a patch sent on linux-input by Sanjay Govind [2], the accelerometer is mapped to ABS_RY for tilt. Interestingly, the Wii U and PS3 dongles share the same VID and PID.

Changes in v2: * Patches hid-sony instead of creating a new driver * Changed memory allocation scheme in case of fail --- drivers/hid/Kconfig | 1 + drivers/hid/hid-ids.h | 3 ++ drivers/hid/hid-sony.c | 112 +++++++++++++++++++++++++++++++++++++++++ 3 files changed, 116 insertions(+)
