2015-09-08drm: Make drm_fb_unregister/remove accept NULL fbDaniel Vetter
These functions are used by drivers to release fbdev emulation buffers. We need to make them resilient to NULL pointers to make the fbdev compile/runtime knobs not cause Oopses on module unload.

2015-09-08drm/fb-helper: Use -errno return in restore_mode_unlockedDaniel Vetter
Using bool and returning true upon error is very uncommon. Also an int return value is actually what all the callers which did check it seem to have expected. v2: Restore hunk misplaced in a rebase, spotted by Rob.

2015-09-08drm/mm: Do DRM_MM_CREATE_TOP adj_start calculation after color_adjustMichel Thierry
The adj_start calculation for DRM_MM_CREATE_TOP should happen after mm->color_adjust. There was an inconsistency between drm_mm_insert_helper_range and drm_mm_insert_helper, as the later was already updating after color_adjust. Didn't spot it before, as color_adjust is only done in systems without LLC. But I'm not aware of anybody using this test case yet.

2015-09-01i915: Set ddi_pll_sel in DP MST pathAnder Conselvan de Oliveira
The DP MST encoder config function never sets ddi_pll_sel, even though its value is programmed in its ->pre_enable() hook. That used to work because a new pipe_config was kzalloc'ed at every modeset, and the value of zero selects the highest clock for the PLL. Starting with the commit below, the value of ddi_pll_sel is preserved through modesets, and since the correct value wasn't properly setup by the MST code, it could lead to warnings and blank screens. commit 8504c74c7ae48b4b8ed1f1c0acf67482a7f45c93 Author: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Date: Fri May 15 11:51:50 2015 +0300 drm/i915: Preserve ddi_pll_sel when allocating new pipe_config Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=91628 Cc: stable@vger.kernel.org # 7e6313a2516d drm/i915: Don't use link_bw for PLL setup Cc: stable@vger.kernel.org Cc: Timo Aaltonen <tjaalton@ubuntu.com> Cc: Luciano Coelho <luciano.coelho@intel.com> Signed-off-by: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com>
