Subject: [PATCH 06/25] drm/fb_helper: Create a wrapper for remove_conflicting_framebuffers
Date: Mon, 13 Jul 2015 12:08:02 +0530	[thread overview]
Message-ID: <1436769501-4105-7-git-send-email-architt@codeaurora.org> (raw)
In-Reply-To: <1436769501-4105-1-git-send-email-architt@codeaurora.org>

Some drm drivers call remove_conflicting_framebuffers. Create a
drm_fb_helper function that wraps around these calls.

This is part of an effort to prevent drm drivers from calling fbdev
functions directly, in order to make fbdev emulation a top level drm
option.
