From 3d41fff3ae3980c055f3c7861264c46c924f3e4c Mon Sep 17 00:00:00 2001 From: Tony Lindgren <tony@atomide.com> Date: Tue, 18 May 2021 10:53:06 +0300 Subject: [PATCH] clocksource/drivers/timer-ti-dm: Drop unnecessary restore The device is not losing context on CPU_CLUSTER_PM_ERROR. As we are only saving and restoring context with cpu_pm, there is no need to restore the context in case of an error. Note that the unnecessary restoring of context does not cause issues, it's just not needed.
