Wysocki [ Upstream commit d46c4c839c20a599a0eb8d73708ce401f9c7d06d ] Commit 03f1444016b7 ("PM: sleep: Fix handling devices with direct_complete set on errors") caused power.is_suspended to be set for devices with power.direct_complete set, but it forgot to ensure the clearing of that flag for them in device_resume(), so power.is_suspended is still set for them during the next system suspend-resume cycle. If that cycle is aborted in dpm_suspend(), the subsequent invocation of dpm_resume() will trigger a device_resume() call for every device and because power.is_suspended is set for the devices in question, they will not be skipped by device_resume() as expected which causes scary error messages to be logged (as appropriate). To address this issue, move the clearing of power.is_suspended in device_resume() immediately after the power.is_suspended check so it will be always cleared for all devices processed by that function.
