From 0c8d604dea437b69a861479b413d629bc9b3da70 Mon Sep 17 00:00:00 2001 From: Jinjie Ruan ruanjinjie@huawei.com Date: Mon, 23 Sep 2024 11:42:50 +0800 Subject: [PATCH] i2c: xiic: Fix pm_runtime_set_suspended() with runtime pm enabled

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.
