From 047a01fdc807ffa461db87e2d30d6d28f95c091a Mon Sep 17 00:00:00 2001 From: Hans Verkuil <hans.verkuil@cisco.com> Date: Tue, 22 Nov 2011 08:23:19 -0300 Subject: [PATCH] [media] omap_vout: add missing OVERLAY_OUTPUT cap and set V4L2_FBUF_FLAG_OVERLAY The omap_vout driver has an output overlay, but never advertised that capability. The driver should also set the V4L2_FBUF_FLAG_OVERLAY flag.
