Could you clarify if this is a fix, or an improvement?

If I understand correctly the discussion at
http://lists.busybox.net/pipermail/buildroot/2022-April/641451.html,
this driver used to require mesa3d+dri+egl (which guaranteed to provide
libgbm), but now only requires libgbm. If this is correct, then this
patch is not a fix, but an improvement, because it makes this package
available in a larger set of configurations.

Could you clarify this?

Interesting, we had a Config.in dependency on mesa, but it was not a
build dependency, but libgbm is?
