Subject: Make unregister_binfmt() return void
X-Git-Tag: v2.6.24-rc1~779
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f6b450d489f2fb4e909447beacad64edb8aa0cda;p=linux-2.6

Make unregister_binfmt() return void

list_del() hardly can fail, so checking for return value is pointless
(and current code always return 0).

Nobody really cared that return value anyway.
