Subject: [media] s5p-mfc: Fix unbalanced call to clock management
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.
