[PATCH] sysfs: sysfs_remove_dir() needs to invalidate the dentry
When calling sysfs_remove_dir() don't allow any further sysfs functions to work for this kobject anymore. This fixes a nasty USB cdc-acm oops on disconnect. Many thanks to Bob Copeland and Paul Fulghum for taking the time to track this down.
