Subject: [PATCH v2] drm/mediatek: fix a typo
Date: Tue, 18 Oct 2016 16:23:59 +0800	[thread overview]
Message-ID: <1476779039-28963-1-git-send-email-bibby.hsieh@mediatek.com> (raw)

If we want to set the hardware OD to relay mode,
we have to set OD_CFG register rather than
OD_RELAYMODE; otherwise, the system will access
the wrong address.

Fixes: 7216436420414144646f5d8343d061355fd23483 ("drm/mediatek: set mt8173 dithering function")
Cc: stable@vger.kernel.org # v4.9+
