From 6f6b287968681f660e151c202765da9f58d3dcba Mon Sep 17 00:00:00 2001 From: Hai Li Date: Thu, 23 Apr 2015 14:13:21 -0400 Subject: drm/msm: Attach assigned encoder to eDP and DSI connectors drm_mode_connector_attach_encoder() function call is missing during eDP and DSI connector initialization. As a result, no encoder is returned by DRM_IOCTL_MODE_GETCONNECTOR system call. This change is to fix this issue.
