Peter Hurley ce7373685e HID: logitech-dj: Fix non-atomic kmalloc in logi_dj_ll_input_event() 
The ll_driver's .hidinput_input_event() method is called from
atomic context [1]. Use GFP_ATOMIC for allocation of the
synthesized hid report.

BUG: sleeping function called from invalid context at /home/peter/src/kernels/next/mm/slub.c:941
