[media] mtk_vcodec_dec: return error at mtk_vdec_pic_info_update()
Gcc 7.1 complains that:
drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c: In function 'mtk_vdec_pic_info_update':
drivers/media/platform/mtk-vcodec/mtk_vcodec_dec.c:284:6: warning: variable 'ret' set but not used [-Wunused-but-set-variable]
int ret;
^~~
Indeed, if debug is disabled, "ret" is never used. The best
fix for it seems to make the fuction to return an error code.
