Merge branch 'pm-runtime' into pm-for-linus
* pm-runtime: PM / Tracing: build rpm-traces.c only if CONFIG_PM_RUNTIME is set PM / Runtime: Replace dev_dbg() with trace_rpm_*() PM / Runtime: Introduce trace points for tracing rpm_* functions PM / Runtime: Don't run callbacks under lock for power.irq_safe set USB: Add wakeup info to debugging messages PM / Runtime: pm_runtime_idle() can be called in atomic context PM / Runtime: Add macro to test for runtime PM events PM / Runtime: Add might_sleep() to runtime PM functions
