Subject: [PATCH 2/9] libata: kill SError clearing in sata_std_hardreset().
Date: Fri, 10 Feb 2006 23:58:48 +0900	[thread overview]
Message-ID: <11395835282675-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11395835282719-git-send-email-htejun@gmail.com>

Don't clear SError in sata_std_hardreset().  This makes hardreset act
identically to ->phy_reset register-wise.
