Yeah, commit f9b0e251dfbf 'drm: make mode_valid callback optional' is
in the drm tree, so this patch needs to go to Dave Airlie (cc'd).
Though Daniel Vetter may want to send it on.

For Dave's benefit, here is the patch again:

From:	Vincent Stehlà <vincent.stehle@xxxxxxxxxxx>
Subject: [PATCH linux-next] imx-drm: imx-tve: remove unused variable
Date:	Sun, 25 May 2014 23:54:14 +0200

Commit f9b0e251dfbf 'drm: make mode_valid callback optional' left variable ret
unused; remove it.

This fixes the following compilation warning:

  drivers/staging/imx-drm/imx-tve.c: In function âimx_tve_connector_mode_validâ:
  drivers/staging/imx-drm/imx-tve.c:252:6: warning: unused variable âretâ [-Wunused-variable]

Hi,

This can be seen with e.g. linux next-20140523 and arm allmodconfig.

Best regards,
