Subject: [PATCH 4.2 069/134] [media] media: am437x-vpfe: Requested frame size and fmt overwritten by current sensor setting

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

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

From: Benoit Parrot <bparrot@...com>

commit f47c9045643f91e76d8a9030828b9fe1cf4a6bcf upstream.

Upon a S_FMT the input/requested frame size and pixel format is
overwritten by the current sub-device settings.
Fix this so application can actually set the frame size and format.

Fixes: 417d2e507edc ("[media] media: platform: add VPFE capture driver support for AM437X")
