The dev_pm_qos_remove_request function can return 1 if "aggregated constraint value has changed" so only negative values should be reported as errors.

Link to v1: https://patchwork.kernel.org/patch/11433131/ I'm not sure this meet that stable kernel standard of "real bug that bothers people" because all this fixes is a spurious dev_warn on device removal. But Sasha Levin's script seem to collect a lot of low-priority fixes anyway.
