[Mesa-dev] [RFC v2 12/22] anv: Set anv_surface::offset earlier

[Louis-Francis Ratté-Boulianne]

From: Chad Versace <chadversary at chromium.org>

Set anv_surface::offset *before* calling add_surface().

No intended change in behavior. This patch prepares for supporting
user-provided surface offsets, a feature required for
VK_MESAX_external_image_dma_buf.
