I recommend to get used with `git grep ...` which is more powerful and much
faster (on a Git index).

	git grep -lw 'u[^3].* usage_id' -- drivers/iio/

for the list of files, and

	git grep -np -w 'u[^3].* usage_id' -- drivers/iio/

for a better view.

(It gives one false positive, though :-)

Jonathan, it seems the missing part of the initial unification. Please, apply
to your testing branch.
