Here is a branch with my work-in-progress thoughts on fixing some of
these module load ordering problems and obviating the need for
cxl_acquire_endpoint():

https://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git/log/?h=for-6.18/cxl-probe-order

Feel free to steal from that branch and take code upstream with my
Co-developed-by. The main missing piece is integration with Terry's
"pdev->is_cxl" enabling to know when it is worth waiting for CXL
scanning and when to fallback to PCIe only.
