[PATCH 4.9 09/28] drm/mediatek: Fix an error code in mtk_hdmi_dt_parse_pdata()

[Greg Kroah-Hartman]

[ 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.
