Subject: pf: add error handling support for add_disk()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4fac63f8a871bc2e38dce4944c9d964a62bac3e6;p=linux.git

pf: 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.
