From 8141f2e9e0ee14e6bdee589d6afb3f415dd22926 Mon Sep 17 00:00:00 2001 From: Libin Yang Date: Tue, 7 May 2019 14:33:11 +0800 Subject: [PATCH] ASoC: codec: hdac_hdmi: no checking monitor in hw_params Some userspace apps, like pulseaudio, may call open, hw_params, prepare to judge whether the pcm is ready or not. Current hdac_hdmi will return -ENODEV if monitor is not connected, which will cause the apps believe the pcm is not ready. Actually PCM for hdmi is ready, even the monitor is not connected. This patch removes the check of monitor presence in hw_params, just like what the legacy HD-Audio driver does.
