[PATCH] media change events - do not emit change event at device add

[PATCH] media change events - do not emit change event at device add

[Kay Sievers]

Hi James,
we like to see this in 2.6.25. There is no need to send out "change"
events immediately after we added a new device. Presetting the state flag
prevents this.

Thanks,
Kay

Subject: [SCSI] media change events - do not emit change event at device add

Initialize the "state changed" flag, so we do not send a change event
immediately after registering a new device.
