Subject: [PATCH v4 1/6] scsi/sd: add error handling support for add_disk()
Date:   Mon, 27 Sep 2021 14:59:53 -0700

Precedence: bulk

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().
