Subject: vulkan/wsi/x11: Set OUT_OF_DATE if wait_for_special_event fails
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6937c613242d646b8c37f01ffd6a02a9b64c8d6c;p=mesa.git

vulkan/wsi/x11: Set OUT_OF_DATE if wait_for_special_event fails

This most likely means we lost our connection to the X server so
OUT_OF_DATE is reasonable.  This was also the one case where we pushed a
UINT32_MAX into the queue without setting an error condition.
