Still can't build, any alternative?

There is no any chance to build it on 6.x kernel?

I managed to make the plugin build again by extending the patch below:

seems to its broken on 5.18.3 :(

The patch @rg209834 posted works all so for me on 5.15.12-arch1-1 (MacBookPro7,1)

The patch @rg209834 posted still works for me on 5.14.16-arch1-1. I'm sure if this patch was integrated into the main pkgbuild we could drop the out of date flag here.

Although flagged as out of date (with comment "package is for an old version of the kernel and does not work anymore") it worked for me with 5.10.60 kernel on old macbook (13" mid 2009 model) with legacy nvidia driver (nvidia-340xx-dkms - 340.108-22). This required the changes mentioned by @sapphire.

Here's a git diff -U1 of the changes that can be applied with patch:

After makepkg -sif, I get /sys/class/backlight/nvidia_backlight.

Finally, I had to add the following to the X11 config file /etc/X11/xorg.conf.d/20-nvidia.conf under Section "Device" to get the screen backlight buttons to work:

Option "Backlight" "nvidia_backlight"

To make it compile/build/work the following changes are needed:

In Makefile: default: $(MAKE) -C $(KDIR) M=$(PWD) SUBDIRS=$(PWD) modules

clean: $(MAKE) -C $(KDIR) M=$(PWD) SUBDIRS=$(PWD) clean

In nvidia_bl.c at line 928 change the name of the function ioremap_nocache to ioremap_cache e.g.
dd->smartdimmer = ioremap_cache(reg_addr, dd->reg_size);
