[PATCH 4.4 072/103] [media] s5p-mfc: Fix unbalanced call to clock management

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marek Szyprowski <m.szyprow...@samsung.com>

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.

Fixes: af93574678108 ("[media] MFC: Add MFC 5.1 V4L2 driver")
