[patch] drm/layerscape: fix a signedness bug

[Dan Carpenter]

"index" needs to be signed for the error handling to work.  Really "ret"
should be an int as well.

Fixes: 109eee2f2a18 ('drm/layerscape: Add Freescale DCU DRM driver')

We seem to be sending duplicates.  I sent another duplicate today.

Could you CC kernel-janitors on static checker fixes so I can monitor
what fixes you send?
