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.

 

--- Vivi Li                                                  2011-09-13 03:16:42

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

Close it.
