scsi_host_lookup — get a reference to a Scsi_Host by host no
struct Scsi_Host * scsi_host_lookup ( | unsigned short hostnum); |
Return value: A pointer to located Scsi_Host or NULL.
The caller must do a scsi_host_put to drop the reference
that scsi_host_get took. The put_device below dropped
the reference from class_find_device.
