Subject: drm/i915: Clear old hw.fb & co. from slave plane's state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 7d8d2cbce5af5ed5a80d5857f0d01d03aaacef71
Patch-mainline: v5.7-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Let's do the intel_plane_copy_uapi_to_hw_state() before we bail out
due to both old and new uapi.crtc being NULL. This will drop the
reference to the old hw.fb for planes that are transitioning from
being a slave plane to simply being disabled.
