Subject: [PATCH 04/12] mce-severity: trivial cleanups
Date: Fri, 27 May 2011 13:06:21 +0900	[thread overview]
Message-ID: <4DDF233D.5020107@jp.fujitsu.com> (raw)
In-Reply-To: <4DDF21DE.9040705@jp.fujitsu.com>

- use BITCLR/BITSET
- coordinate message pattern
- use m for struct mce
- minor cleanup for severities_debugfs_init()

Logic is not changed.
