[PATCH] R3964: fix GFP_KERNEL allocations in timer function
In the error case, add_msg() gets called from timer functions, so should
be using GFP_ATOMIC instead of GFP_KERNEL.
Ref: http://bugzilla.kernel.org/show_bug.cgi?id=6659. Thanks to Christian
Werner <chw@ch-werner.de> for reporting, and for the initial fix.
