Subject: [PATCH 2.6.20] pvrusb2: use ARRAY_SIZE macro when appropriate (2)
Date: Mon, 5 Feb 2007 18:53:33 +0200
Message-ID: <20070205165333.GB3896@Ahmed> (raw)
In-Reply-To: <20070205165134.GA3896@Ahmed>

Hi all,
A patch to use ARRAY_SIZE already defined in kernel.h. This patch is
a complementry (and does not include) the one sent one week earlier.

Signed-off-by: Ahmed S. Darwish <darwish.07@gmail.com>

It seems that the earlier grep expression I used to produce the first
patch didn't catch the below occurences. Sorry for the incovenience.

Patch is compile tested.
