Subject: [PATCH 00/10] drm/msm: fix bind error handling

I had reasons to look closer at the MSM DRM driver error handling and
realised that it had suffered from a fair amount of bit rot over the
years.

Unfortunately, I started fixing this in my 6.2 branch and failed to
notice two partial and, as it turned out, broken attempts to address
this that are now in 6.3-rc1.

Instead of trying to salvage this incrementally, I'm reverting the two
broken commits so that clean and backportable fixes can be added in
their place.

Included are also two related cleanups.
