This patch reorganises the sa1111_resume() function in a manner the spinlock happens after calling the sa1111_wake(). This fixes two bugs: 1) This function called sa1111_wake() which tried to claim the same spinlock the sa1111_resume() already claimed. This would result in certain deadlock. Original idea for this part: Russell King <rmk+kernel@arm.linux.org.uk> 2) The function didn't unlock the spinlock in case the chip didn't report correct ID.
