X-Git-Tag: v4.19.252~22
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=377ca648a129cce6420e9f226f65e6e62234cc08;p=thirdparty%2Fkernel%2Fstable.git

video: of_display_timing.h: include errno.h

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")
