Message-ID: <b1050f72fcade3475ff10d1e0ef1cb4d0cfde0c0.camel@perches.com>
Date: Sun, 05 Apr 2020 08:52:35 -0700
From: Joe Perches <joe@...ches.com>

Subject: [PATCH] exfat: Use a more common logging style
Remove the direct use of KERN_<LEVEL> in functions by creating
separate exfat_<level> macros.
Miscellanea:
o Remove several unnecessary terminating newlines in formats
o Realign arguments and fit to 80 columns where appropriate
