Bug description:
[Impact]
HP G12 laptops on AMD platform with audio codec RTK ALC3315+CS35L56
amplifier, the MIC-Mute function is working but the LED state is not toggled
accordingly.
[Fix]
The HP laptops on AMD platform needs a upstream patch e2cda4617656 ("ASoC:
amd: acp: Refactor dmic-codec platform device creation") landed since 6.14-rc6
to correctly create a dmic-codec device instead of a audio card driven by
snd_acp_legacy_mach.
[Test Case]
1. Boot and log into the HP G12 laptops powered by AMD.
2. Issue command `alsa-info` and check the generated output file
3. Make sure no card named snd_acp_legacy_mach listed in ALSA modules
4. press mic-mute hot-key and check if mic-mute is enabled or not by the OSD
icon.
5. The mic-mute led should be ON when mic-mute enabled, OFF when disabled.
[Where problems could occur]
The patch identify the audio device for ACP7.0 correctly. Needs to verify on
new AMD platforms which supports ACP7.0 devices.
