3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dmitry Torokhov <dmitry.torok...@gmail.com>
commit 28a2a2e1aedbe2d8b2301e6e0e4e63f6e4177aca upstream.
We need to make sure we allocate absinfo data when we are setting one of
EV_ABS/ABS_XXX capabilities, otherwise we may bomb when we try to emit this
event.
