Message-Id: <3dcb6d8f61280d20b8d893ba0b95b4b318570aed.1525964382.git.joe@perches.com>

Subject: [PATCH 02/18] lib: Use pr_fmt
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 lib/ 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 logging output now is
prefixed with the appropriate KBUILD_MODNAME.
Miscellanea:
o Simplify debugging macros to only require a single function definition
by moving #define DEBUG into the definition and removing the empty
function definition
o Function alignment neatening
o Use %s, __func__ instead of embedding function names as strings
o Add missing newline terminations
Signed-off-by: Joe Perches <joe@...ches.com>
