+Subject: zink: allow KMS-only display fd to fall through to default
+ Vulkan device selection
+
+When MESA_LOADER_DRIVER_OVERRIDE=zink is used with a GBM device created
+on a KMS-only display node (e.g. /dev/dri/card1 bound to verisilicon-dc
+on StarFive JH7110), zink_render_rdev() returned -1 because the device
+has no render node, causing zink_drm_create_screen() to bail and GBM
+initialisation to fail.
+
+Treat the missing render node as "no specific device requested" instead
+of an error.  zink_picks_device() then returns false, and choose_pdev()
+falls back to default Vulkan physical-device selection, picking
+whichever ICD vkEnumeratePhysicalDevices() reports first (PowerVR on
+JH7110).  Cross-device dma-buf import via VK_KHR_external_memory_fd
+takes care of getting the rendered frame onto the display controller.
