Subject: [PATCH AUTOSEL 4.19 02/19] scsi: 3w-9xxx: Avoid disabling device if failing to enable it
Date: Wed, 12 Oct 2022 20:26:01 -0400	[thread overview]
Message-ID: <20221013002623.1895576-2-sashal@kernel.org> (raw)
In-Reply-To: <20221013002623.1895576-1-sashal@kernel.org>

From: Letu Ren <fantasquex@gmail.com>

[ Upstream commit 7eff437b5ee1309b34667844361c6bbb5c97df05 ]

The original code will "goto out_disable_device" and call
pci_disable_device() if pci_enable_device() fails. The kernel will generate
a warning message like "3w-9xxx 0000:00:05.0: disabling already-disabled
device".

We shouldn't disable a device that failed to be enabled. A simple return is
fine.
