Commit 2353f2bea ("HID: protect hid_debug_list") introduced mutex
locking around debug_list access to prevent SMP races when debugfs
nodes are being operated upon by multiple userspace processess.
mutex is not a proper synchronization primitive though, as the hid-debug
callbacks are being called from atomic contexts.
We also have to be careful about disabling IRQs when taking the lock
to prevent deadlock against IRQ handlers.
Benjamin reports this has also been reported in RH bugzilla as bug #958935.
