  "message": "PM / Domains: Fix handling of wakeup devices during system resume\n\nDuring system suspend pm_genpd_suspend_noirq() checks if the given\ndevice is in a wakeup path (i.e. it appears to be needed for one or\nmore wakeup devices to work or is a wakeup device itself) and if it\nneeds to be \"active\" for wakeup to work.  If that is the case, the\nfunction returns 0 without incrementing the device domain\u0027s counter\nof suspended devices and without executing genpd_stop_dev() for the\ndevice.  In consequence, the device is not stopped (e.g. its clock\nisn\u0027t disabled) and power is always supplied to its domain in the\nresulting system sleep state.\n\nHowever, pm_genpd_resume_noirq() doesn\u0027t repeat that check and it\nruns genpd_start_dev() and decrements the domain\u0027s counter of\nsuspended devices even for the wakeup device that weren\u0027t stopped by\npm_genpd_suspend_noirq().  As a result, the start callback may be run\nunnecessarily for them and their domains\u0027 counters of suspended\ndevices may become negative.  Both outcomes aren\u0027t desirable, so fix\npm_genpd_resume_noirq() to look for wakeup devices that might not be\nstopped by during system suspend.\n\nSigned-off-by: Rafael J.
