Hi Marcel,

I noticed that rfcomm_dev_del() may be called twice if
RFCOMM_HANGUP_NOW flags is used with RFCOMMRELEASEDEV ioctl.

I made a patch that checks if dev is still in the device list before
calling deleting device.

The checking is done now in rfcomm_release_dev. Maybe better place would
be rfcomm_dev_del?
