Thanks, going over what went in I see drmGetMinorNameForFD and
the OpenBSD drmGetDevice2 paths need to be adjusted to have the correct
minor for the control/render nodes.

ie

base = drmGetMinorBase(type);
if (min < base)
	return error;

min -= base;

I'll send another patch for this.

And the common code could be split into a shared function?

drmGetDeviceNameFromFd2 would do the same thing as
drmGetDeviceNameFromFd on OpenBSD as far as I can tell so that could be
another shared function instead of the current "missing implementation"
warning.  Or should drmGetDeviceNameFromFd purposefully not handle
render/control nodes?
