Subject: virgl: Deduplicate checks for resource caching
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8eb8222c102ee6cd38a01e7df952ea87e1ca4f42;p=mesa.git

virgl: Deduplicate checks for resource caching

Also fixes a missed check for VIRGL_BIND_CUSTOM in one of the duplicate
code snippets.

Note that legacy fences also use VIRGL_BIND_CUSTOM, but we ensured they
don't go through the cache in the previous commit.
