Using my Veyron Jerry Chromebook wiht latest kernel I found that the
speakers doesn't work. Bisect points to this patch as the offending
commit. However your changes looks reasonable the fact is that
reverting the patch makes the audio work again on my device. I need to
dig a bit more into the issue, but meanwhile, any idea on what is
happening ? Can I ask which device did you test?
PS: Sorry for the noise if you received the email twice.
