Subject: [PATCH] block/swim3: add error handling support for add_disk()
Git-commit: 2d4bcf76429713c2ca0093c11b5b75072db95a50
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.
