Subject: [PATCH 2/3] ALSA: hda/realtek - Enable micmute LED on and HP system
Date:   Thu, 30 Apr 2020 16:32:52 +0800
Message-Id: <20200430083255.5093-2-kai.heng.feng@canonical.com>
In-Reply-To: <20200430083255.5093-1-kai.heng.feng@canonical.com>
References: <20200430083255.5093-1-kai.heng.feng@canonical.com>

Precedence: bulk

Though the system uses DMIC, headset mic still uses the HDA, let's use
GPIO 0x1 to control the micmute LED.

The micmute LED GPIO has a different polarity to the mute LED GPIO, we
can use the newly added micmute_led_polarity to indicate that.
