The set_fmt operations updates the sensor format only when the image format
is changed. When only the image sizes gets changed, the format do not get
updated causing the sensor to always report the one that was previously in
use.
Without this patch, updating frame size only fails:
[fmt:UYVY8_2X8/640x480@1/30 field:none colorspace:srgb xfer:srgb ...]
With this patch applied:
[fmt:UYVY8_2X8/1024x768@1/30 field:none colorspace:srgb xfer:srgb ...]
Fixes: 6949d864776e ("media: ov5640: do not change mode if format or frame
interval is unchanged")
