[Mesa-dev] [PATCH v2 04/10] etnaviv: increment correct seqno for external resources

[Lucas Stach]

If we import a dma-buf with a sampler/pixel pipe incompatible modifier,
the imported buffer will end up in an external resource view. As
resource_changed signals the change of the imported resource, we need
to update the external view seqno, instead of the base resource seqno.
