2009-10-02[SCSI] qla2xxx: Fix NULL ptr deref bug in fail path during queue createAnirban Chakraborty1-2/+4
Current code attempts to clean up resources when queue create fails and there it invokes queue free call with a (NULL) pointer to the queue which could not be allocated in the first place. Fix it by returning directly without invoking the queue free call as no resources has been allocated at that point of time.

In fabric-login based on iop BIT_8 firmware notifies presence of a FCP2 device and not necessarily a TAPE device. So instead of setting FCF_TAPE_PRESENT flag there we set it using scsi_device->type after mid-layer scan recognises "type" of the device. It also adds a new flag FCF_FCP2_DEVICE for any future use.
