[PATCH 4.4 21/58] drm: rcar-du: fix backport bug

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>

In the backport of commit 4f7b0d263833 ("drm: rcar-du: Simplify and fix
probe error handling"), which is commit 8255d26322a3 in this tree, the
error handling path was incorrect.  This patch fixes it up.
