Marek Vašut f26a43c5a1 ARM: 6146/1: sa1111: Prevent deadlock in resume path
commit 3defb24761 upstream.

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.

   Original idea for this part: Julia Lawall <julia@diku.dk>
