Subject: [PATCH 0/3] drm/msm: Handle component bind failures a bit better

I somewhat accidently injected an error in the DPU KMS init that caused it to
fail and a handful of NULL deferences and errors ended up popping out. Here are
some fixes in the interest of robustness.

Jordan Crouse (3):
  drm/msm/dpu: Fix error recovery after failing to enable clocks
  drm/msm/dpu: Avoid a null de-ref while recovering from kms init fail
  drm/msm/adreno: Call pm_runtime_force_suspend() during unbind
