Parallel port LED driver 0.0.1

Parallel port LED driver package contains a LED subsystem device driver for the Linux operating system. The code was written for Linux version 2.6.22.

The module takes 1 parameter, which is parled_port_nr, which is the parallel port number on which the LEDs are connected.

I do not take responsibility for any damage to your computer that could result from your usage of the attached parallel port pinout. Also I don't take responsibility for the device driver, which the GPL luckily clarifies already.

Pinout:

You should probably add some ~500 ohm resistors before the LEDs, I'm just gonna say that I didn't and it works anyways (quite bright LEDs).
