Revision ca0bf64d99f6e3f6e2fe2585e52a0ac57354beac authored by Thadeu Lima de Souza Cascardo on 02 February 2010, 21:44:17 UTC, committed by Linus Torvalds on 03 February 2010, 02:11:23 UTC 
pktcdvd: removing device does not remove its sysfs dir
 
This is the counterpart to cba767175becadc5c4016cceb7bfdd2c7fe722f4
("pktcdvd: remove broken dev_t export of class devices").  Device is not
registered using dev_t, so it should not be destroyed using device_destroy
which looks up the device by dev_t.  This will fail and adding the device
again will fail with the "duplicate name" error.  This is fixed using
device_unregister instead of device_destroy.
