Hi Aaron,
I can't apply your patch. Your MUA seems to wrap the mail. Maybe you
want to use "git send-email" instead.
Btw, the fisrt part of the mail should be your commit message. You can
put your explanation below the "---" line. And hid drivers are
maintained by Jiri Kosina <jkosina@xxxxxxx>, you might also CC Jiri next
time.
Thanks.
br,
jj
