Subject: OMAP: DSS2: VENC: Add missing start/stop_device calls
X-Git-Tag: firefly_0821_release~7613^2~1156^2~20^2~69
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=14572c6356dc4361231ee8f4402468c1f36d2c34;p=firefly-linux-kernel-4.4.55.git

OMAP: DSS2: VENC: Add missing start/stop_device calls

VENC code was missing omap_dss_start/stop_device calls. This didn't
cause any problems as VENC could not be compiled as a module, but
nevertheless it's better to add the calls.
