Subject: intel/aubinator: Gracefully handle dynamic state not being available
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=69fa3fb77f298f717be9a45b3989d039071ffe15;p=mesa.git

intel/aubinator: Gracefully handle dynamic state not being available

Some older versions of the Vulkan driver didn't properly tag dynamic
state as needing to be captured.  Also, this prevents crashes when
looking at dumps on older kernels.
