[igt-dev] [PATCH i-g-t v2 2/2] kms_hdr: Fix bpc-switch tests on AMD hardware

[Jeremy Cline <jcline@redhat.com>]

Kernel commit b836a274b797 ("drm/amdgpu/dc: Require primary plane to be
enabled whenever the CRTC is") causes the bpc-switch tests to fail,
since the primary plane fb is being removed, which leads to the next
atomic commit failing with -EINVAL.

This stops the removal of the primary plane fb before switching to 10
bits per component and the test now runs successfully.
