Subject: media: ov5640: fix auto controls values when switching to manual mode
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=a8f438c684eaa4cbe6c98828eb996d5ec53e24fb;p=openwrt%2Fstaging%2Fblogic.git

media: ov5640: fix auto controls values when switching to manual mode

When switching from auto to manual mode, V4L2 core is calling
g_volatile_ctrl() in manual mode in order to get the manual initial value.
Remove the manual mode check/return to not break this behaviour.
