From a9c8088c7988e3a8a364cac9c26eba9ee2ea6153 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Wed, 25 Apr 2018 11:53:40 +0200 Subject: [PATCH] i2c: i801: Don't restore config registers on runtime PM Restoring configuration registers is only needed when we hand control to the firmware. This is never the case with runtime power management. The device will autosuspend whenever not used, so avoid useless register writes by defining suspend/resume only, and not runtime_suspend/runtime_resume.
