Coding device driver for a minor device.

I have done modules.

Now the problem is that I have 2 pushbuttons that I would like to read.
Looking in the device list I see dev 10, which has a lot of - let us call it
miscellaneous - content. This one seems to fit here. Maybe as a minor 185 or
186.
But how do I locate the device driver for device major 10?

I am certain there is a simple way - somebody knows it?


Sinserely,
