Subject: drm/tilcdc: Fix check for remote port parent
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a3479c4fa0f149d9f3f6f88c173c4f4cd07a1714;p=linux-beck.git

drm/tilcdc: Fix check for remote port parent

In function tilcdc_get_external_components the check for
the remote port parent is not correct. We need a '||' instead of
an '&&'.
