Hi Markus
I tried the test of this patch.
However, I was not able to apply a patch.
Is this patch a patch for which kernel(commit number)?
cheers,
Goda

Hello Yusuke,
I did pull the kernel from sh-2.6.git on 13.07.10
The latest commits were
9b0d8f82dd4d4ae53050a800e4ce5dd2b1828ad7 "sound/soc/sh/siu: Fixed undefined dma_length of scatter gather list"
36239c6704b71da7fb8e2a9429e159a84d0c5a3e "sh: add sh7757lcr board support"
Bye,
Markus
