Subject: drm/i915: Remove KMS Kconfig option

Since we only support modesetting by default (disabling modesetting on
the command line prevents i915.ko from loading), having a parameter to
disable modesstting by default is superfluous, i.e. saying
CONFIG_DRM_I915_KMS=n is equivalent to CONFIG_DRM_I915=n.

Subject: drm/panel: Add Samsung prefix to panel drivers

The likelihood of getting a large number of panel drivers from different
vendors is quite high. Add a prefix to the two existing Samsung panel
drivers to set a guideline for future patch submissions. Using vendor
prefixes consistently should allow a cleaner organization of the tree.

From 330b48bd700d5cdc3d1922c4e50f0626ab8ec002 Mon Sep 17 00:00:00 2001
From: Thierry Reding <treding@nvidia.com>
Date: Tue, 14 Apr 2015 15:39:51 +0200
Subject: drm/bridge: Add vendor prefixes

Use vendor prefixes for Kconfig symbols and filenames. This should make
it easier to identify the various bridge drivers and to organize the
directory.

v2: fix object name for dw-hdmi (Fabio Estevam)
