Subject: [PATCH 4.19 124/220] media: ov5640: fix framerate update

From: Hugues Fruchet <hugues.fruchet@...com>

[ Upstream commit 0929983e49c81c1d413702cd9b83bb06c4a2555c ]

Changing framerate right before streamon had no effect,
the new framerate value was taken into account only at
next streamon, fix this.
