Expected results:
No errors

Additional info:
Looking at the fedora distgit, the module has regressed with the commit-id d906ff02 "Rebase the bfq patch"
that removes the "ENV{DEVTYPE}=="disk", \" condition. Adding the condition again discard the error.


Can you provide more information about why this rule has regressed again in your setup ? This is not the first time I'm reporting this issue and there is a need to clear it for good.

Thanks in advance.
