[snipped a number of Q&A]

Thanks for your previous answers, now I have a couple more questions:

Which is the proper way of dealing with multifunction devices?
(I'm talking about a sound card with a joystick port)

Right now the driver searches for two independent devices which works
ok except for the fact that I need to make some connection between joystick
and sound card (I need to access the sound card pci_dev->driver_data from the
joystick
initialization routine). I could always look for another device on the same
slot but who guarantees this has already been initialized?

The pci device layout is (lspci -vv):
00:13.0 Multimedia audio controller: Creative Labs SB Live! (rev 04)
Subsystem: Unknown device 1102:0020
Flags: bus master, medium devsel, latency 64, IRQ 19
I/O ports at ef40
Capabilities: <available only to root>

00:13.1 Input device controller: Creative Labs SB Live! Daughterboard (rev 01)
Subsystem: Unknown device 1102:0020
Flags: bus master, medium devsel, latency 64
I/O ports at eff0
Capabilities: <available only to root>
