drm/omap: Use new drm_fb_helper functions
Use the newly created wrapper drm_fb_helper functions instead of calling core fbdev functions directly. They also simplify the fb_info creation. v3: - Update error handling for new drm_fb_helper funcs. Check using IS_ERR() instead of checking for NULL. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> v2: - No changes Cc: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
