Thanks for the update!

This breaks both falconide and pata_falcon, as it marks the resource
busy:
ide: Falcon IDE controller
falconide: resources busy
and
pata_falcon: Atari Falcon PATA controller
pata_falcon: resources busy
For pata_falcon, that regression can easily be fixed by merging both patches.
For falconide, I think the sensible thing to do is just remove the driver.
But before that, the defconfigs should be updated to use pata_falcon
instead of falconide.
For the actual code changes:
