[SRU][J/HWE-5.17/OEM-5.17/HWE-5.15][PATCH 0/1] Audio mute key (f5) LED and Mic mute key (f8) LED are no function on HP 440/450/640/650 G9

[Jeremy Szu]

[Impact]
The audio mute key (F5) and mic-mute LED (F8) don't work on some HP 440/450/640/650 G9 laptops.

[Fix]
The HP ProBook 440/450 G9 and EliteBook 640/650 G9 have multiple
motherboard design and they are using different subsystem ID of audio
codec. Add the same quirk for other MBs.

[Test]
After applying the fix, the mute LEDs are working.

[Where problems could occur]
It's low risk as it's specific ID for HP new machines. If the HP ships other machines using same SSID, then the LED may not work on those machines.
