To: dri-devel; +Cc: intel-gfx
This removes the need to separately track fb changes i915.
That will be done as a separate commit, however.
Changes since v1:
- Add dri-devel to cc.
- Fix a check in intel's prepare and cleanup fb to take rotation
into account.
Changes since v2:
- Split out i915 changes to a separate commit.

To: dri-devel; +Cc: intel-gfx
atomic->disabled_planes is a hack that had to exist because
prepare_fb was only called when a new fb was set. This messed
up fb tracking in some circumstances like aborts from
interruptible waits. As a result interruptible waiting in
prepare_plane_fb was forbidden, but other errors could still
cause frontbuffer tracking to be messed up.
Now that prepare_fb is always called, this hack is no longer
required and prepare_fb may fail without consequences.

I'd probably prefer to see the change to call them unconditionally
(regardless of fb != NULL) in a separate patch, but with or without:
