There are variants of this by class/bus/driver and all of them are introduced
as separate patches with the respective users. If we do for this, we have to
do the same for other matches as well.

i.e, [ device_match_by_attr + class_find_device_by_attr & users + 
driver_find_device_by_attr & users + bus_find_device_by_attr & users ]

And that becomes a large chunk, which could make the review painful.

If you would still like that approach, I could do that in the next revision.

Cheers
Suzuki
