From: Mike Christie Date: Sat, 20 Nov 2021 10:49:17 -0600 Subject: scsi: core: sysfs: Fix setting device state to SDEV_RUNNING Git-commit: eb97545d6264b341b06ba7603f52ff6c0b2af6ea Patch-mainline: v5.16-rc3 References: git-fixes This fixes an issue added in commit 4edd8cd4e86d ("scsi: core: sysfs: Fix hang when device state is set via sysfs") where if userspace is requesting to set the device state to SDEV_RUNNING when the state is already SDEV_RUNNING, we return -EINVAL instead of count. The commmit above set ret to count for this case, when it should have set it to 0.
