Subject: [PATCH 16/53] ALSA: x86: Move the global underrun_count to struct snd_intelhad
Date: Thu,  2 Feb 2017 18:02:30 +0100
Message-ID: <20170202170307.24484-18-tiwai@suse.de> (raw)
In-Reply-To: <20170202170307.24484-1-tiwai@suse.de>

The last one is in intel_hdmi_audio.c, underrun_count: this can be
embedded in snd_intelhad object.
