From cd9ebdbc0541b4e8ee145c81642d68332f79b932 Mon Sep 17 00:00:00 2001 From: Michael Grzeschik Date: Tue, 3 Aug 2010 06:37:54 -0300 Subject: [PATCH] V4L/DVB: mx2_camera: fix for list bufnum in frame_done_emma The emma uses bufnum 1 and 0. This patch tells the bufqueue to change the next buffer to the next one and not the current one. Otherwise the BUG_ON above will trigger everytime.
