Follow-ups
--- Scott Jiang 2011-08-15 03:40:11
this is a common issue in latest trunk. Dep file is correct, but modprobe can't
probe modules with indirect dependency.
--- Sonic Zhang 2011-08-31 22:49:50
Fixed by update example/depmod.pl
--- Vivi Li 2011-09-01 22:44:17
I check the ssm2602 log, and still fail to work.

ASOC framework is different from V4L2.
snd_bf5xx_i2s has no dependency to snd-ssm2602 in the new ASOC framework since
2.6.37.

Dependency in vs6624 test is OK due to this bug is fixed.
Close it.
