__scsi_device_lookup - find a device given the host (UNLOCKED)
2. SYNOPSIS ▲
struct scsi_device * __scsi_device_lookup(struct Scsi_Host * shost , uint channel , uint id , uint lun );
3. ARGUMENTS ▲
SCSI host pointer
SCSI channel (zero if only one channel)
SCSI target number (physical unit number)
SCSI Logical Unit Number
4. DESCRIPTION ▲
Looks up the scsi_device with the specified channel, id, lun for a given host. The returned scsi_device does not have an additional reference. You must hold the hostAqs host_lock over this call and any access to the returned scsi_device.
5. NOTE ▲
The only reason why drivers would want to use this is because they need to access the device list in irq context. Otherwise you really want to use scsi_device_lookup instead.
