Subject[alsa, pnp] more on opl3sa2
Date
more tests with snd-opl3sa2. i have to use the paramers to modprobe since pnp
doesn't work. the reason:
pnpc_register_driver sets driver.bus to its own static struct which doesn't
have a device list. driver_attach tries to scan this device list and compare
with the drivers device list. since there's no one for the bus it fails, the
driver can't see it's devices.

Call stack:
driver_attach
bus_add_driver
driver_register
pnpc_register_driver
alsa_card_opl3sa_init

ok, tried by hand with the config data from bios/lspnp:
# modprobe snd-opl3sa2 isapnp=0 port=0x538 wss_port=0x530 sb_port=0x220 fm_port=0x388 midi_port=0x330 irq=5 dma1=0 dma2=1

100% reproducible.

machine is a toshiba tecra 8000 laptop (p3-500), kernel is 2.5.59 + vmlinux.lds.h patch +
sound-firmware-load-fix + jaroslav's driver patch + adam's pnp.h id len patch.

kernel config: no acpi, _all_ pnp options enabled. soundcore compiled in, alsa as module.
