Justin T. Gibbs 58d246367e adv_pci.c: 
adw_pci.c:
	Update comments describing supported chips/cards.

adwcam.c:
adwlib.c:
adwlib.h:
	Handle more error return codes from the firmware.

	Break out the bus reset code into its own function.

	Usa a constant for the bus reset hold delay.

	Fix an interrupt race problem in adw_idle_cmd_send by
	incorporating the poll loop for command completion.
