USB: fix oops on disconnect in cdc-acm
This patch fixes an oops caused when during an unplug a device's table of endpoints is zeroed before the driver is notified. A pointer to the endpoint must be cached. this fixes a regression caused by commit 5186ffee2320942c3dc9745f7930e0eb15329ca6 Therefore it should go into 2.6.31 Signed-off-by: Oliver Neukum <oliver@neukum.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
