Hi,
This is because of a newly merged patch from Armin Wolf:
https://lore.kernel.org/platform-driver-x86/20240226193557.2888-2-W_Armin@gmx.de/
You can comment that line or apply that patch to your tree to make it
compile. Also, you'll probablyneed to change the call to wmidev_block_set in
casper_query function with wmi_set_block (which is now deprecated).

No, there isn't a tool yet but controlling leds via sysfs ispretty easy.
For example, if you wanted to change the left led zone's color to red:
```
# echo 0xff0000 > /sys/class/leds/casper\:\:kbd_zoned_backlight-left/multi_intensity
```
And don't forget that all leds' initial brightnesses are 0.
Also, I'm planning to add support for this API in OpenRGB.

For laptops with 11th gen processors or newer: yes.
For laptops with 10th gen processors or older: no, there are 4 power
profiles for these laptops (High Performance, Gaming, Text Mode andPower
save).

Yes, power-profiles-daemon is already integrated with platform_profile.
