[Mesa-dev] [PATCH v4 4/7] etnaviv: implement resource_changed to invalidate internal resources derived from imported buffers

[Philipp Zabel]

Implement the resource_changed pipe callback to invalidate internal
resources derived from imported buffers. This is needed to update the
texture for re-imported renderables.
