Message-ID: <lsq.1374674565.756748076@decadent.org.uk> Date: Wed, 24 Jul 2013 15:02:45 +0100 From: Ben Hutchings <ben@...adent.org.uk> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org CC: akpm@...ux-foundation.org, "Takashi Iwai" <tiwai@...e.de> Subject: [24/85] ALSA: hda - Cache the MUX selection for generic HDMI 3.2.49-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@...e.de> commit bddee96b5d0db869f47b195fe48c614ca824203c upstream. 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().
