[PATCH openEuler-1.0-LTS] PM: sleep: core: Clear power.must_resume in noirq suspend error path
by Xinyu Zheng 04 Nov '25

From: "Rafael J. Wysocki" <rafael.j.wysocki(a)intel.com> mainline inclusion from mainline-v6.18-rc1 commit be82483d1b60baf6747884bd74cb7de484deaf76 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID4AQL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ---------------------------------------------------------------------- If system suspend is aborted in the "noirq" phase (for instance, due to an error returned by one of the device callbacks), power.is_noirq_suspended will not be set for some devices and device_resume_noirq() will return early for them. Consequently, noirq resume callbacks will not run for them at all because the noirq suspend callbacks have not run for them yet. If any of them has power.must_resume set and late suspend has been skipped for it (due to power.smart_suspend), early resume should be skipped for it either, or its state may become inconsistent (for instance, if the early resume assumes that it will always follow noirq resume). Make that happen by clearing power.must_resume in device_resume_noirq() for devices with power.is_noirq_suspended clear that have been left in suspend by device_suspend_late(), which will subsequently cause device_resume_early() to leave the device in suspend and avoid changing its state.
