+Subject: [PATCH] bindings: python: tests: disable device before releasing the
+ bank
+
+Linux kernel commit 8bd76b3d3f3a ("gpio: sim: lock up configfs that an
+instantiated device depends on") uncovered an issue in Python bindings
+tests where the GPIO simulator device is not disabled before removing its
+configfs entries. Reorder the operations in chip_finalize() in order to
+disable the device first (if needed) before releasing any other
+resources.
+
+Upstream-Status: Submitted [https://lore.kernel.org/all/20250203-fix-gpiosim-in-bindings-v1-2-d2c9e0f3a29d@linaro.org/]
