Kernel module compilation error on 6.1.0-rc1

[Slaviusz]

Since commit 94e371e73fbe44ed338b51739ed2d3fa7b233bf4 I'm receiving an error trying to compile the kernel module.

make -j1 -C /lib/modules/6.1.0-rc1-tkg-cfs/build M=/root/CoreFreq modules

Thanks, I see the issue is a constant name collision with Kernel header file.

I will boot that Kernel RC to program a fix.

CoreFreq version 1.92.3 is fixing the issue which I found to also exists on Linux Kernel 6.0.3

Thanks, everything works ok now.
