From: Cornelia Huck <[email protected]> the current driver tree contains the removal of subsys.rwsem. Unfortunately, this breaks qeth. However, it should be no problem to fix the walking of the devices for /proc/qeth: No need to take subsys.rwsem during walking the devices, driver_find_devices() should already suffice.
