RGB Keyboard not working on lts kernel arch linux #200

Model: Nitro AN515-45

Count of keyboard RGB zones: 4

Count of Cpu Fans: 1

Count of Gpu Fans: 1

RGB keyboard works? Yes

Turbo button turn on fans? Not Tested

Turbo button turn on LED? Not Tested

Turbo button activates overclock? Not Tested

I'm using x211321's Plasma 6 Applet to interface with the module, but it only seems to work on the regular linux kernel. When I boot with the lts kernel it gives me an error saying that the keyboard device doesn't exist. I have to use the lts kernel because there is currently a problem with the main kernel not waking from suspend when using Nvidia drivers. I installed this via the ExpediaOS Repo. Is there a way to install it for the linux-lts kernel manually?

I tried going through the manual install (one-time), and when I run sudo ./install.sh it gives the error "insmod: ERROR: could not insert module src/facer.ko: Unknown symbol in module". I tried it on both the lts kernel and the regular kernel, and it works on the regular kernel.

Same here, I'm using a PH315-55 though, but same effect that yours, if I use the current 6.11.6 kernel, it works, however if I use the LTS Kernel 6.6.59 it stops working.

For a temporary fix I reverted back to 1186522 commit for it to work again.

Can confirm this issue with kernel 6.6.59-1-lts. when I ran install.sh this was the output

4d7d033 is the latest commit that works. these kinds of errors start with 8bb294a
I've looked at the code before and after, and as far as I can tell all the (err -2) are from those functions not being in the LTS headers. I was able to temporarily fix this by adding these starting at line 1163

int platform_profile_remove()
{
	return 0;
}

int platform_profile_register(struct platform_profile_handler* platform_profile_handler)
{
	return 0;
}

void platform_profile_notify()
{
}

It still puts out a bunch of errors, but it still seems to work with these modifications
I'm not sure if there is a way to do conditional function declaration at runtime, The only other fix I can think of long term is some kind of conditional compilation based on whether or not you're using a LTS kernel.
