Subject: [PATCH v2 14/25] drm/exynos: Use new drm_fb_helper functions
Date: Wed, 22 Jul 2015 12:29:50 +0530 [thread overview]
Message-ID: <1437548401-10125-15-git-send-email-architt@codeaurora.org> (raw)
In-Reply-To: <1437548401-10125-1-git-send-email-architt@codeaurora.org>
Use the newly created wrapper drm_fb_helper functions instead of calling
core fbdev functions directly. They also simplify the fb_info creation.
COMPILE TESTED ONLY.
