Subject: V4L/DVB (11464): gspca - m5602-mt9m111: Set the cached v4l2 ctrl values
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=dd3ec39871ba83fb47364a26b1caaac4494deb7b;p=mv-sheeva.git

V4L/DVB (11464): gspca - m5602-mt9m111: Set the cached v4l2 ctrl values

When we resume the machine we want the previously set values, not the default
values. Fix this for the mt9m111 sensor
