These are easier to read if you ignore the 80-char limit.
Unless Jassi's object that is.

Add your entry on top, to maintain sort order.

Better use of_device_match_data() and get the string directly (or NULL).

I didn't apply the patch to look for myself, but please ensure to
maintain indentation to follow the parenthesis on the line before.

Add it one line up and you'll maintain partial sorting...
