Subject: [RFC PATCH 03/37] drm: mode: Allow NULL modes for equality check
Date: Thu, 19 Mar 2015 04:33:02 +0000 [thread overview]
Message-ID: <1426739616-10635-3-git-send-email-daniels@collabora.com> (raw)
In-Reply-To: <1426739616-10635-1-git-send-email-daniels@collabora.com>
Since we're now using mode == NULL to represent disabled, it's not
wholly surprising that we'd want to compare NULL modes.
