Driver not compiling on Kernel 6.12.4, "aml_deinit" and "aml_init" undefined

[werefkin]

Hi I did not succeed to compile the driver upon the kernel update on Arch. I get:

  MODPOST /home/werefkin/drivers/macbook12-bluetooth-driver/build/bluetooth/Module.symvers
ERROR: modpost: "aml_deinit" [/home/werefkin/drivers/macbook12-bluetooth-driver/build/bluetooth/hci_uart.ko] undefined!
ERROR: modpost: "aml_init" [/home/werefkin/drivers/macbook12-bluetooth-driver/build/bluetooth/hci_uart.ko] undefined!

make[1]: Leaving directory '/usr/lib/modules/6.12.4-arch1-1/build'
make: *** [Makefile:10: all] Error 2

any idea of how to resolve the issue?

I was able to compile the driver for Kernel 6.12 (Manjaro) by updating patch_bluetooth/Makefile:

Yes, I can confirm that it works. Could you please explain the changes for the unfamiliar (me)? Have there been any related changes to the kernel recently?
