+Subject: [PATCH] drisw: move zink down the list below the sw drivers.
+
+We don't ever want drisw path picking zink as the driver,
+we can revisit this when the penny wrapper work gets further
+along.
+
+This selection causes systems with nvidia/intel dual-gpus
+to try and pick the intel gpu for rendering in the nvidia
+context if there is no nvidia GL driver or accel doesn't work.
+
+This is a partial revert of the original commit.
+
+Fixes: 4a3b42a717ce ("drisw: Prefer hardware-layered sw-winsys drivers over pure sw")
