From f2005e1777614b65d1970924ca1b61e4caccb0d3 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 13 Mar 2008 12:32:43 -0700 Subject: [PATCH] block: floppy: fix rmmod lockup Floppy rmmod locks up when no such hardware was initialized, since there is nobody to wake the remove code up. Remove the completion, because release is called during platform_unregister anyway.
