drm/mediatek: fix a typo of DISP_OD_CFG to OD_RELAYMODE
If we want to set the hardware OD to relay mode, we have to set DISP_OD_CFG register rather than OD_RELAYMODE; otherwise, the system will access the wrong address. Change-Id: Ifb9bb4caa63df906437d48b5d5326b6d04ea332a Fixes: 7216436420414144646f5d8343d061355fd23483 ("drm/mediatek: set mt8173 dithering function") Cc: stable@vger.kernel.org # v4.9+ Signed-off-by: Bibby Hsieh <bibby.hsieh@mediatek.com> Acked-by: CK Hu <ck.hu@mediatek.com>
