From: Paulo Zanoni <paulo.r.zanoni at intel.com> Hi This week I sent a patch called "drm/i915: propagate errors from intel_dp_init_connector" to fix a Haswell bug that was preventing my machine from booting. Chris provided a nice suggestion for it, so this series should implement his suggestion, but split in a few patches. While writing this code I also spotted a few other things, so there are some patches for them here. Patch 3 is the real bug fix and patches 4 & 5 implement Chris's suggestions. Patch 1 is another bug fix and patches 2, 6, 7 & 8 are my bikesheds for the current code. Thanks, Paulo Paulo Zanoni (8): drm/i915: don't check encoder at DP connector destroy() drm/i915: extract intel_edp_init_connector drm/i915: propagate errors from intel_dp_init_connector drm/i915: fix the "ghost eDP" connector unwind path drm/i915: fix the "ghost eDP" encoder unwind path drm/i915: check the return value of intel_dp_i2c_init drm/i915: invert the verbosity of intel_enable_fbc drm/i915: rename intel_dp_destroy to intel_dp_connector_destroy drivers/gpu/drm/i915/intel_ddi.c | 7 +- drivers/gpu/drm/i915/intel_dp.c | 180 +++++++++++++++++++++++---------------- drivers/gpu/drm/i915/intel_drv.h | 2 +- drivers/gpu/drm/i915/intel_pm.c | 3 +- 4 files changed, 113 insertions(+), 79 deletions(-) -- 1.8.1.2
