[alsa-devel] Where to find recent fix for HD-Audio runtime PM?

Hi Takashi,

If convenient, would you please point out your previous patches to make HD-Audio runtime PM stable? I guess 'ALSA: hda - Refactor pm notification in hda_codec.c' is only one of them.

We observed audio failure (dead communication) after S3 if runtime PM is enabled on Haswell with Kernel v3.9. We hope to back port your previous fix and further check this issue.

Many thanks! Mengdong
