| |
3.6.11.9-rc1 stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@suse.de>
[ Upstream commit bddee96b5d0db869f47b195fe48c614ca824203c ]
When a selection to a converter MUX is changed in hdmi_pcm_open(), it should be cached so that the given connection can be restored properly at PM resume. We need just to replace the corresponding snd_hda_codec_write() call with snd_hda_codec_write_cache().
