Subject: ps3disk: add error handling support for add_disk()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ff4cbe0fcf5d749f76040f782f0618656cd23e33;p=linux.git

ps3disk: add error handling support for add_disk()

We never checked for errors on add_disk() as this function
returned void. Now that this is fixed, use the shiny new
error handling.
