[SRU][Trusty][Wily][Xenial][lts-u][lts-v][PATCH 0/1] Input: xpad - correctly handle concurrent LED and FF requests

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1564901

== SRU Justification ==
xpad rumble causes full system hang.  

The bug can be reproduced by playing the game Borderlands 2 while having a wired 
xbox controller connected. The system will randomly freeze.

Mainline commit 7fc595f4c02636eadaeeecfe7bbc45b57c173004 fixes this bug.  It is in
mainline as of 4.6-rc1.  It cherry picks and builds cleanly.


== Fix ==
commit 7fc595f4c02636eadaeeecfe7bbc45b57c173004

    Input: xpad - correctly handle concurrent LED and FF requests


== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
