Thanks everyone for the replies but i think for this trivial problem i don't need to backport the kernel.Anyway now i know the answer for my posted question.I have kept backporting as an excersie as my assignment which i will do in due period of time. ------- Original Message------- Sender: Mark Brown<broonie@xxxxxxxxxxxxxxxxxxxxxxxxxxx> Date: Apr 20, 2010 01:59 (GMT+09:00) Title: Re: No shutdown code in soc-core.c On Mon, Apr 19, 2010 at 03:10:55PM +0100, Liam Girdwood wrote: > Ah, your kernel is very old.

Actually, IME it's probably as easy to just backport current ASoC to 2.6.29 if you're doing anything non-trivial - the backport is very straightforward for most platforms and the benefits of the enhancements in ASoC are well worth the effort. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
