Subject: [PATCH AUTOSEL 4.14 035/186] scsi: ufs: Fix ufshcd_probe_hba() reture value in case ufshcd_scsi_add_wlus() fails
Date: Fri, 14 Feb 2020 11:14:44 -0500 [thread overview]
Message-ID: <20200214161715.18113-35-sashal@kernel.org> (raw)
In-Reply-To: <20200214161715.18113-1-sashal@kernel.org>
From: Bean Huo <beanhuo@micron.com>
[ Upstream commit b9fc5320212efdfb4e08b825aaa007815fd11d16 ]
A non-zero error value likely being returned by ufshcd_scsi_add_wlus() in
case of failure of adding the WLs, but ufshcd_probe_hba() doesn't use this
value, and doesn't report this failure to upper caller. This patch is to
fix this issue.
Fixes: 2a8fa600445c ("ufs: manually add well known logical units")
