Subject: [PATCH 1/3] ALSA: hda/realtek - Introduce polarity for micmute LED GPIO
Date:   Thu, 30 Apr 2020 16:32:51 +0800
Message-Id: <20200430083255.5093-1-kai.heng.feng@canonical.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently mute LED and micmute LED share the same GPIO polarity.

So split the polarity for mute and micmute, in case they have different
polarities.
