Subject: [PATCH 02/15] drm/mode: move framebuffer_free up above framebuffer_init
Date: Fri, 15 Apr 2016 15:10:33 +1000 [thread overview]
Message-ID: <1460697046-23781-3-git-send-email-airlied@gmail.com> (raw)
In-Reply-To: <1460697046-23781-1-git-send-email-airlied@gmail.com>
From: Dave Airlie <airlied@redhat.com>
A later patch will use it in framebuffer_init, and I want
to keep the diff cleaner.
