4.2.8-ckt3 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Chen-Yu Tsai <wens@xxxxxxxx> commit 768acf46e1320d6c41ed1b7c4952bab41c1cde79 upstream. The driver allocates the spinlock but fails to initialize it correctly. The kernel reports a BUG indicating bad spinlock magic when spinlock debugging is enabled. Call spin_lock_init() on it to initialize it correctly.
