Subject: [PATCH 3/3] driver core: auxiliary bus: minor coding style tweaks

From: Greg KH <[email-masked]>
Date: Fri, 4 Dec 2020 12:44:24 +0100

From: Greg Kroah-Hartman <[email-masked]>

For some reason, the original aux bus patch had some really long lines
in a few places, probably due to it being a very long-lived patch in
development by many different people.  Fix that up so that the two files
all have the same length lines and function formatting styles.
