Subject: [PATCH 1/2] drm/edid: Use unsigned int in drm_add_modes_noedid()
Date: Tue, 25 Mar 2025 17:27:04 -0400	[thread overview]
Message-ID: <20250325212823.669459-2-lyude@redhat.com> (raw)
In-Reply-To: <20250325212823.669459-1-lyude@redhat.com>

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.
