Subject: vulkan/wsi: use the drmGetDevice2() API
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c210d0c3b72ac426ee18b43f036e1a852a39950b;p=mesa.git

vulkan/wsi: use the drmGetDevice2() API

On older kernels, the drmGetDevice() call will wake up all the GPUs
on the system, while fetching the PCI revision.

Use the 2 version of the API and pass flags == 0, so we don't fetch the
device PCI revision, since we don't need that information.
