Subject: [PATCH] ps3vram: add error handling support for add_disk()
Git-commit: 3c30883acab1d20ecbd3c48dc12b147b51548742
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.
