Input: replace spin_lock_bh with spin_lock_irqsave in ml_ff_playback
ml_ff_playback() uses spin_(un)lock_bh. However this function is
called with interrupts disabled from erase_effect() in
drivers/input/ff-core.c:196.
This is not permitted, and will result in a WARN_ON in the bottom
half handling code. This patch changes this function to just use
spin_lock_irqsave() instead, solving the problem and simplifying
the locking logic.
This was reported as entry #106559 in kerneloops.org
