Follow-ups

--- Cliff Cai 2009-07-03 05:39:19

the dependencies are broken by mainline recently.

now we have to install snd-soc-core first.

modprobe snd-soc-core

modprobe snd-ad1980

modprobe snd-pcm-oss(for oss-based applications)

Cliff:

Can you describe exactly what you mean?

depmod (busybox's perl script) should be able to figure this out, and add

things in the correct order.

--- Cliff Cai 2009-07-06 22:54:00

it seems the moudules.dep is not correctly generated. I will check what has

changed.

--- Mike Frysinger 2009-07-08 22:04:26

the modules.dep file looks fine. snd-soc-ad1980.ko depends on snd-soc-core.ko

and snd-soc-core.ko depends on kernel/sound/ac97_bus.ko. looks like modprobe

itself isnt processing the dependency list properly.

--- Mike Frysinger 2009-07-09 00:32:46

nm, i was looking at the wrong module. snd-ad1980 != snd-soc-ad1980.

should be fixed now in trunk and branch by having depmod.pl run through the

dependencies recursively.

--- Vivi Li 2009-07-27 00:22:35

OK now. Close it.
