From 2bea241a03ab67fc841c626c25f09108ffda7a35 Mon Sep 17 00:00:00 2001 From: Libin Yang Date: Tue, 12 Jan 2016 11:13:26 +0800 Subject: [PATCH] ALSA: hda - add hdmi_pcm to manage hdmi pcm related features Use struct hdmi_pcm wrapper for hdmi pcm management. All PCM related features, like jack, will be put in this structure.
