Subject: V4L/DVB (11465): gspca - m5602-s5k4aa: Set all v4l2 ctrls on sensor init.
X-Git-Tag: v2.6.31-rc1~297^2~405
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d4a389a39bb9586219641144ab0c79706bbc8bcc;p=karo-tx-linux.git

V4L/DVB (11465): gspca - m5602-s5k4aa: Set all v4l2 ctrls on sensor init.

Reset all v4l2 ctrls on the s5k4aa init. The prevents all ctrls to be reset
during resume from ram.
