From a0aa44e7364f840031998b30ddb0f5de1686dfec Mon Sep 17 00:00:00 2001 From: Jinjie Ruan Date: Mon, 23 Sep 2024 12:00:13 +0800 Subject: [PATCH] spi: spi-imx: Fix pm_runtime_set_suspended() with runtime pm enabled BugLink: https://bugs.launchpad.net/bugs/2089884 [ Upstream commit b6e05ba0844139dde138625906015c974c86aa93 ] It is not valid to call pm_runtime_set_suspended() for devices with runtime PM enabled because it returns -EAGAIN if it is enabled already and working. So, call pm_runtime_disable() before to fix it.
