Subject: [PATCH] scsi: sd: Add error handling support for add_disk()
Git-commit: 2a7a891f4c406822801ecd676b076c64de072c9e
Patch-mainline: v5.16-rc1
References: jsc#PED-1183
We never checked for errors on add_disk() as this function returned
void. Now that this is fixed, use the shiny new error handling.
As with the error handling for device_add() we follow the same logic and
just put the device so that cleanup is done via the scsi_disk_release().
