From 758cc55ce3d5d79e8f98adbd03ad2cd29133af33 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 18 Feb 2025 21:13:09 +0100 Subject: PM: runtime: Introduce pm_runtime_blocked() Introduce a new helper function called pm_runtime_blocked() for checking the power.last_status value indicating whether or not enabling runtime PM for the given device has been blocked (which happens in the "prepare" phase of system-wide suspend if runtime PM is disabled for the given device at that point).
