Subject: [PATCH 4.19 10/31] video: of_display_timing.h: include errno.h

From: Hsin-Yi Wang <hsinyi@...omium.org>

commit 3663a2fb325b8782524f3edb0ae32d6faa615109 upstream.

If CONFIG_OF is not enabled, default of_get_display_timing() returns an
errno, so include the header.

Fixes: 422b67e0b31a ("videomode: provide dummy inline functions for !CONFIG_OF")
