From 8e25a0e266b05f414a63bf04b30d9a7e085e94fc Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Thu, 16 Feb 2017 16:29:04 +0530 Subject: [PATCH] drm/msm/dsi: Fix bug in dsi_mgr_phy_enable A recent commit introduces a bug in dsi_mgr_phy_enable. In the non dual DSI mode, we reset the mdsi (master DSI) PHY. This isn't right since master and slave DSI exist only in dual DSI mode. For the normal mode of operation, we should simply reset the PHY of the DSI device (i.e. msm_dsi) corresponding to the current bridge. Usage of the wrong DSI pointer also resulted in a static checker warning. That too is resolved with this fix.
