Subject[PATCH 3.18 33/83] Input: xpad - fix clash of presence handling with LED setting
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit fbe6a3114471cccaeaeabfa56937731503ece545 ]

Do not call xpad_identify_controller at init with wireless devices: it
conflicts with the already sent presence packet and will be called by
xpad360w_process_packet as needed anyway.
