4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>
commit a5cb00eb4223458250b55daf03ac7ea5f424d601 upstream.
Clock should be turned off after calling s5p_mfc_init_hw() from the
watchdog worker, like it is already done in the s5p_mfc_open() which also
calls this function.
