Subject[PATCH v2] media: rcar-vin: Update crop and compose settings for every s_fmt call
Date
The crop and compose settings for VIN in non mc mode werent updated
in s_fmt call this resulted in captured images being clipped.

With the below sequence on the third capture where size is set to
640x480 resulted in clipped image of size 320x240.

high(640x480) -> low (320x240) -> high (640x480)

This patch makes sure the VIN crop and compose settings are updated.

Fixes: 104464f573d ("media: rcar-vin: Do not reset the crop and compose rectangles in s_fmt")
