From db18644f90e664bf30f58cf9b8bc879598bff62f Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 13 Oct 2011 16:12:29 +0300 Subject: [PATCH] OMAPDSS: DSI: remove dsi_get_num_lanes_used There's no longer need for the dsi_get_num_lanes_used function, so it can be removed. The lane check in dsi_init_display() can be removed as the validity of the config will be verified when parsing it.
