Subject: drm/mediatek: Fix an error code in mtk_hdmi_dt_parse_pdata()
X-Git-Tag: v4.9.175~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=65dabcd68459e0debca3cbbb7e7610546ae3087a;p=platform%2Fkernel%2Flinux-amlogic.git

drm/mediatek: Fix an error code in mtk_hdmi_dt_parse_pdata()

[ Upstream commit 2d85978341e6a32e7443d9f28639da254d53f400 ]

We don't want to overwrite "ret", it already holds the correct error
code.  The "regmap" variable might be a valid pointer as this point.
