None of the coding style document is an actual requirement Greg.
It's all rules of thumb.  Useful rules, but not hard and fast right?

To me, the biggest issue with this code isn't whether or not the
code is aligned at open parentheses or stays within 80 columns,
but is the use of 30+ character length identifiers.

Using identifiers of that length makes using 80 column, or even
100 column length lines infeasible.

Perhaps seeing if include/linux/greybus/greybus_protocols.h
could be updated to use shorter length identifiers might be useful.

The median length identifier there is ~25 chars long and the
maximum length identifier is ~50 chars.
