From e02b42f3fc56c67c6f81caea6911f83f18ccb4d4 Mon Sep 17 00:00:00 2001 From: Yang Yingliang Date: Sun, 25 Sep 2022 10:12:58 +0800 Subject: [PATCH] pinctrl: ocelot: add missing destroy_workqueue() in error path in ocelot_pinctrl_probe() [ Upstream commit 8ada020ade3bc4125b639a1dca50a6df687dd986 ] Using devm_add_action_or_reset() to make workqueue device-managed, so it can be destroy whenever the driver is unbound.
