Subject: [PATCH 07/15] hisi_sas: fix phy8 linkrate calculation in phy_up_v2_hw()
Date: Tue, 6 Sep 2016 23:36:17 +0800	[thread overview]
Message-ID: <1473176185-217808-8-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1473176185-217808-1-git-send-email-john.garry@huawei.com>

In function phy_up_v2_hw(), we needlessly recalculate the
phy linkrate for all phys, and the calculation is incorrect
for phy8, so remove this code.
