Build fails on kernel version 6.1.1-1-MANJARO - no acpi_video_set_dmi_backlight_type about faustus HOT 5 OPEN

Same for Arch Linux 6.1.1.
The function 'acpi_video_set_dmi_backlight_type' was changed or removed from the Kernel.

from faustus.

Currently on kernel 6.1.3 running on FA506QM and was able to get faustus working with the following change

3378   │ #if LINUX_VERSION_CODE < KERNEL_VERSION(6,1,1)
3379   │     /* Some Asus desktop boards export an acpi-video backlight interface,
3380   │        stop this from showing up */
3381   │     chassis_type = dmi_get_system_info(DMI_CHASSIS_TYPE);
3382   │     if (chassis_type && !strcmp(chassis_type, "3"))
3383   │         acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);
3384   │ 
3385   │     if (asus->driver->quirks->wmi_backlight_power)
3386   │         acpi_video_set_dmi_backlight_type(acpi_backlight_vendor);
3387   │ 
3388   │     if (asus->driver->quirks->wmi_backlight_native)
3389   │         acpi_video_set_dmi_backlight_type(acpi_backlight_native);
3390   │ #endif

However I cannot ensure this works on all ASUS devices.
Please use at your own risk.

EDIT: I've also tracked down what commit on the Linux kernel made faustus fail to compile, and it was this commit.

I recommend enabling the modules for limited keyboard control. This is a temporary solution until someone can find a fix.
/etc/modprobe.d/faustus.conf

#blacklist asus_wmi
#blacklist asus_nb_wmi

I downgraded the kernel and the linux-headers to 6.0.12 and it works fine for now until it will be fixed

According to a comment on stickied issue #47, faustus may no longer be required on kernel versions >= 6.1. For those distros which roll their own kernels instead of using the vanilla kernel, it may take a while before the distro-maintainer version of kernel 6.1 is made available.

For those already on kernel version >= 6.1, I guess that it might be worth trying the asus driver version in the kernel instead of faustus compiled from this repo...
