ARM: 6146/1: sa1111: Prevent deadlock in resume path
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 <[email protected]>
2) The function didn't unlock the spinlock in case the chip didn't report
correct ID.
Original idea for this part: Julia Lawall <[email protected]>
