This is a note to let you know that I've just added the patch titled ALSA: hda/realtek - Enable micmute LED on and HP system to the 5.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: alsa-hda-realtek-enable-micmute-led-on-and-hp-system.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 9940c6ab39d054d15ece5a4d7fc0f605834613e9 Author: Kai-Heng Feng <kai.heng.feng@xxxxxxxxxxxxx> Date: Thu Apr 30 16:32:52 2020 +0800 ALSA: hda/realtek - Enable micmute LED on and HP system [ Upstream commit 3e0650ab26e2010ee312311612e40e076ed1feca ] 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.
