Message-ID: <20070302005615.4f53acb8@lxorguk.ukuu.org.uk>
Date: Fri, 2 Mar 2007 00:56:15 +0000
From: Alan <alan@...rguk.ukuu.org.uk>
To: akpm@...l.org, jgarzik@...ox.com, linux-kernel@...r.kernel.org,
linux-ide@...r.kernel.org
Subject: [PATCH] libata: dev_config does not need ap and adev passing
It used to be impossible to get from ata_device to ata_port but that is
no longer true. Various methods have been cleaned up over time but
dev_config still takes both and most users don't need both anyway. Tidy
this one up
