Fix: rhgndf@7be98c3

[Vini98br]

@mati75 this commit fixed the make command errors but when running the next command of the tutorial: insmod fl2000.ko && insmod it66121.ko, it gave me the following error:

And when running only sudo insmod it66121.ko it crashed my entire computer

As my computer crashed I cant show the make command log when i first ran it, but when i run it now, it logs it:

This happened to me too

Whoops, only reading this now 😅 Apologies to everyone whose computer has crashed on my behalf. I've only made this to compile. This was achieved by including guards around few key functions which have been deprecated in 5.12 and then life got in the way of properly figuring out their replacements.
