3.16.49-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpen...@oracle.com>
commit d0a67c372df410b579197ea818596001fe20070d upstream.
We should change this post-op to a pre-op because we want the loop to
exit with "timeout" set to zero.
Fixes: 0a89b55364e0 ("nuc900/rtc: change the waiting for device ready
implement")
