🐞 Bugfixed kernel module on newer kernels #528

[Rikj000]

Part of #528

Fixes make compilation on newer Linux kernels, as described by @briefnotion here:
#528 (comment)

On Kernel:

• 6.6.62+rpt-rpi-2712: I was able to make the kernel module without issues
• 6.12.25+rpt-rpi-2712: I ran into make compilation issues and required this patch

Additionally this MR includes .gitattributes to enforce line endings as LF,
which is default on Linux, thus development on Windows won't screw up the files with CRLF.

@jgarff are you considering merging these? NEed help testing/reviewing?

[Rikj000]

@Loufe, I think this project currently has little maintenance and is reaching end of life,
due to Raspberry Pi's introduction of PioLib on RPi 5 and above,
which allows for easy software based PWM LED control on all GPIOs.
See: https://www.raspberrypi.com/news/piolib-a-userspace-library-for-pio-control/

Imo it makes little sense to keep maintaining this library, when the official RPi team offers a great alternative.
I've already switched to PioLib, and it works quite well.

Still @jgarff thank you for all your work thus far though! ❤️
