[PATCH 01/18] kernel: Use pr_fmt

From: Joe Perches
Date: Thu May 10 2018 - 11:46:20 EST

Sometime in the future, it would be useful to convert pr_fmt from a
default simple define to use a default prefix with KBUILD_MODNAME.

There are files in kernel/ that use pr_<level>, some with an embedded
prefix, that also do not have a specific pr_fmt define.

Add pr_fmt for those files.

There are some differences in output as some messages are now prefixed
with their KBUILD_MODNAME.

Miscellanea:

o Align multiline statements to open parenthesis
o Wrap and realign arguments to 80 columns where sensible
o Coalesce formats
