Subject: [PATCH AUTOSEL 5.4 062/205] scsi: hisi_sas: Don't create debugfs dump folder twice
Date: Thu, 16 Jan 2020 11:40:37 -0500
Message-ID: <20200116164300.6705-62-sashal@kernel.org> (raw)
In-Reply-To: <20200116164300.6705-1-sashal@kernel.org>

From: Xiang Chen <chenxiang66@hisilicon.com>

[ Upstream commit 35160421b63d4753a72e9f72ebcdd9d6f88f84b9 ]

Due to a merge error, we attempt to create 2x debugfs dump folders, which
fails:
[  861.101914] debugfs: Directory 'dump' with parent '0000:74:02.0'
already present!

This breaks the dump function.

To fix, remove the superfluous attempt to create the folder.

Fixes: 7ec7082c57ec ("scsi: hisi_sas: Add hisi_sas_debugfs_alloc() to centralise allocation")
