Subject: [PATCH] ps3disk: add error handling support for add_disk()
Git-commit: ff4cbe0fcf5d749f76040f782f0618656cd23e33
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.
