Is there a problem with repeat implementation in input core that
requres custom-made repeater here?

The code looks a bit dirty (old code commented out, C++ style comments).

If this is really needed - msecs_to_jiffies().

Can we spell it out: atarikbd or atari_kbd?

It looks like this driver is not using standard input event codes. If
Roman does not want to adjust keymaps on Amiga and Atari that should
be handled in legacy keyboard driver (drivers/char/keyboard.c). As it
is programs using /dev/input/eventX have no chance of working.

No need to count, input core takes care of this.

Input core already logs every input device registered, do we need to
repeat it in the driver?
