I wasn't aware, that pm_runtime_irq_safe() basically breaks runtime
PM until Tony's fix for musb (even though it's logical when thinking
about it). Currently omap-ssi and omap-ssi-port make use of
pm_runtime_irq_safe().
Since pm_runtime_get_sync/pm_runtime_put_sync is called from
tasklets in omap-ssi (and omap-ssi-port) it cannot be simply
removed. So fixing PM for the ssi controller requires reworking
the driver in a non trivial way.
