[PATCH] fix for udev-094

from udev's release notes:

"udev 094
========
The built-in MODALIAS key and substitution is removed.
(...)
udev 080
========
(...)
MODALIAS and $modalias is not needed and will be removed from one of
the next udev versions, replace it in all rules with ENV{MODALIAS} or
the sysfs "modalias" value."

here is a patch to fix this issue
