From: Chen-Yu Tsai <wens@xxxxxxxx> This patch has been added to the 4.1 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 768acf46e1320d6c41ed1b7c4952bab41c1cde79 ] 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.
