Subject: [PATCH AUTOSEL 4.19 3/6] drm/exynos: vidi: fix a wrong error return

From: Inki Dae <inki.dae@...sung.com>

[ Upstream commit 4a059559809fd1ddbf16f847c4d2237309c08edf ]

Fix a wrong error return by dropping an error return.

When vidi driver is remvoed, if ctx->raw_edid isn't same as fake_edid_info
then only what we have to is to free ctx->raw_edid so that driver removing
can work correctly - it's not an error case.
