[Mesa-dev] [PATCH] gallium/util: Allow pipe_resource_reference to be inlined again

[Michel Dänzer]

From: Michel Dänzer <michel.daenzer at amd.com>

It calling itself recursively prevented it from being inlined, resulting
in a copy being generated in every compilation unit referencing it. This
bloated the text segment of the Gallium mega-driver *_dri.so by ~5%,
and might also have impacted performance.

Fixes: ecd6fce2611e ("mesa/st: support lowering multi-planar YUV")
