[PATCH 4.19 110/110] media: ov5640: fix auto controls values when switching to manual mode

[Greg Kroah-Hartman]

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hugues Fruchet <hugues.fruchet@xxxxxx>

commit a8f438c684eaa4cbe6c98828eb996d5ec53e24fb upstream.

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.
