Subject: [KJ] [PATCH] [trivial] drivers/ide/legacy/hd.c: Array size
Date: Tue, 05 Jun 2007 09:37:10 +0000 [thread overview]
Message-ID: <200706051137.11564.lists-receive@programmierforen.de> (raw)
This patch replaces an array size calculation in drivers/ide/legacy/hd.c
that was done using sizeof with the ARRAY_SIZE macro.
Tested by compilation on an i386 box using "allyesconfig".
Diffed against Linus' git-tree.
