Subject: Revert "drm/i915/bios: Split parse_driver_features() into two parts"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 5da3f1bfb88ed59e43d9b52529321c20199e8826 which is
commit c3fbcf60bc74b630967f291f47f0d9d0de6fcea7 upstream.
This is part of a series of i915 patches that were backported to 5.19.12
but found to be incomplete and caused problems on many systems so they
are being reverted.
