Subject: vulkan/wsi: initialise image_index to 0 in x11_manage_fifo_queues
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2c020dbf063b55d96b1e799fb8dd6ec335b84c33;p=mesa.git

vulkan/wsi: initialise image_index to 0 in x11_manage_fifo_queues

Supresses a maybe-uninitialized warning with GCC 8.

Note: image_index should always be initialised due to the result check,
      but the compiler doesn't see that.
