While running the kernel with the mutex debugging enabled, I noticed the
warning reported in the first commit (that the bridge's hpd_mutex is
unitialized). Additional research revealed that we do not add and remove
internal drm_bridges in the msm drm driver. Fix this now.

Dmitry Baryshkov (4):
  drm/msm/hdmi: properly add and remove created bridges
  drm/msm/dsi: properly add and remove created bridges
  drm/msm/dp: properly add and remove created bridges
  drm/msm: unregister all internal bridges
