As far as I can tell, device sdhci-pci hasn't been in a release, and we
can still keep it out of 2.5:
* Created in commit 224d10f, v2.3.0.
* Made unavailable in commit 1910913, v2.3.0
* Made available in commit 5ec911c, not yet released.
I'll post a patch making it unavailable again right away, to give you
options.
