From 7e47c211953bd8e396b168eba2c288ea6aec20ef Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Wed, 28 Sep 2011 16:19:52 -0500 Subject: [PATCH] drivers/video: fsl-diu-fb: remove unused panel operating mode support The MFB_TYPE_xxx macros indicate different "operating modes" of each AOI, but this feature is not actually used in the driver. The mfb_index.type field is always set to MFB_TYPE_OUTPUT, so just delete it and any code that references it.
