Subject: [PATCH 03/18] maccess: remove duplicate kerneldoc comments
Date: Wed, 13 May 2020 18:00:23 +0200	[thread overview]
Message-ID: <20200513160038.2482415-4-hch@lst.de> (raw)
In-Reply-To: <20200513160038.2482415-1-hch@lst.de>

Many of the maccess routines have a copy of the kerneldoc comment
in the header.  Remove it as it is not useful and will get out of
sync sooner or later.
