/**
* at_probe - Device Initialization Routine
* @pdev: PCI device information struct
* @ent: entry in at_pci_tbl
*
* Returns 0 on success, negative on failure
*
* at_probe initializes an adapter identified by a pci_dev structure.
* The OS initialization, configuring of the adapter private structure,
* and a hardware reset occur.
