Subject: media: v4l2_driver: Supplement the missing runtime pm get ops on more than once strea... 
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=135da7576122c38df4d803b713d94561a84a75d7;p=platform%2Fkernel%2Flinux-starfive.git

media: v4l2_driver: Supplement the missing runtime pm get ops on more than once stream_on cases.

For example, if we run stf_isp_ctrl & v4l2test at the same time,
s_stream for sensor will be called twice,
so that rpm should be got twice too.
