From e9a164e367f039629fd5466a79b9f495646e1261 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Thu, 14 Sep 2023 22:31:04 +0200 Subject: [PATCH] clk: imx: imx8: Fix an error handling path in imx8_acm_clk_probe() If an error occurs after a successful clk_imx_acm_attach_pm_domains() call, it must be undone. Add an explicit error handling path, re-order the code and add the missing clk_imx_acm_detach_pm_domains() call.
