[PATCH 6.0 801/862] scsi: 3w-9xxx: Avoid disabling device if failing to enable it
From: Greg Kroah-Hartman
Date: Wed Oct 19 2022 - 06:35:35 EST
From: Letu Ren <fantasquex@xxxxxxxxx>
[ 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.
