Brightness and External Mic Fix

[nycxbro527]

Just install your EFI on my T430 and running 10.15.7 - Thanks! Looked at drasbeck's EFI (https://github.com/drasbeck/macos-thinkpad-t430), and came up with 2 fixes to your DSDT.aml patches. Still not able to get my DP to HDMI cable to work though...

--BRIGHTNESS FIX --
#fn keys (F8 and F9)
into method label _Q15 replace_content
begin
    Notify(_SB.PCI0.LPC.KBD, 0x0205)\n
    Notify(_SB.PCI0.LPC.KBD, 0x0285)\n
end;
into method label _Q14 replace_content
begin
    Notify(_SB.PCI0.LPC.KBD, 0x0206)\n
    Notify(_SB.PCI0.LPC.KBD, 0x0286)\n
end;

--EXTERNAL MIC FIX--

Inject Audio info

into method label _DSM parent_label HDEF remove_entry;
into device label HDEF insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
Return (Package()\n
{\n
"layout-id", Buffer() { 29, 0x00, 0x00, 0x00 },\n
"hda-gfx", Buffer() { "onboard-1" },\n
"PinConfigurations", Buffer() { },\n
//"MaximumBootBeepVolume", 77,\n
})\n
}\n
end;

into method label _DSM parent_label HDAS remove_entry;
into device label HDAS insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
Return (Package()\n
{\n
"layout-id", Buffer() { 28, 0x00, 0x00, 0x00 },\n
"hda-gfx", Buffer() { "onboard-1" },\n
"PinConfigurations", Buffer() { },\n
//"MaximumBootBeepVolume", 77,\n

}\n
