driver core: fix namespace issue with devices assigned to classes
- uses a kset in "struct class" to keep track of all directories belonging to this class - merges with the /sys/devices/virtual logic. - removes the namespace-dir if the last member of that class leaves the directory. There may be locking or refcounting fixes left, I stopped when it seemed to work with network and sound modules. :) From: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
