    Subject[PATCH v1] media: ov8856: Fix Bayer format dependance on mode
    Date
    The Bayer GRBG10 mode used for earlier modes 3280x2460 and
    1640x1232 isn't the mode output by the sensor for the
    3264x2448 and 1632x1224 modes.

    Switch from MEDIA_BUS_FMT_SGRBG10_1X10 to MEDIA_BUS_FMT_SBGGR10_1X10
    for 3264x2448 & 1632x1224 modes.

    This patch is sent out after Dongchun Zhu clarified the Bayer
    modes used by different sensor configuration in the below thread.
