Subject: [PATCH 1/2] drm/edid: Use unsigned int in drm_add_modes_noedid()
A negative resolution doesn't really make any sense, no one goes into a TV
store and says "Hello sir, I would like a negative 4K TV please", that
would make everyone look at you funny.
So, let's make these parameters a bit more reasonable and ensure that
they're unsigned - which makes the resulting rust bindings for this
function a bit easier to understand and work with.
