[Patch driver tree] qeth: Remove usage of subsys.rwsem

[Cornelia Huck <cornelia.huck@de.ibm.com>]

Hi,

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.
