From 903cfafe087452e080cea6e30439e7052d1198b6 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 18 Apr 2019 13:39:33 +0200 Subject: [PATCH] ACPI / LPSS: Use acpi_lpss_* instead of acpi_subsys_* functions for hibernate [ Upstream commit c8afd03486c26accdda4846e5561aa3f8e862a9d ] Commit 48402cee6889 ("ACPI / LPSS: Resume BYT/CHT I2C controllers from resume_noirq") makes acpi_lpss_{suspend_late,resume_early}() bail early on BYT/CHT as resume_from_noirq is set. This means that on resume from hibernate dw_i2c_plat_resume() doesn't get called by the restore_early callback, acpi_lpss_resume_early(). Instead it should be called by the restore_noirq callback matching how things are done when resume_from_noirq is set and we are doing a regular resume. Change the restore_noirq callback to acpi_lpss_resume_noirq so that dw_i2c_plat_resume() gets properly called when resume_from_noirq is set and we are resuming from hibernate. Likewise also change the poweroff_noirq callback so that dw_i2c_plat_suspend gets called properly.
