Cada vez que la plataforma pasa a bajo consumo, las rutinas de suspensi\u00f3n/reinicio de PM llaman a __dwc2_lowlevel_hw_enable -> devm_add_action_or_reset(). Esto agrega un nuevo devres cada vez. Esto tambi\u00e9n puede ocurrir en tiempo de ejecuci\u00f3n, ya que dwc2_lowlevel_hw_enable() puede llamarse desde udc_start(). Esto se puede ver con el seguimiento: - echo 1 > /sys/kernel/debug/tracing/events/dev/devres_log/enable - ir a bajo consumo - cat /sys/kernel/debug/tracing/trace Se encuentra una nueva entrada \"ADD\" en cada ciclo de bajo consumo: ... devres_log: 49000000.usb-otg ADD 82a13bba devm_action_release (8 bytes) ... devres_log: 49000000.usb-otg ADD 49889daf devm_action_release (8 bytes) ... Aqu\u00ed se aborda un segundo problema: - regulator_bulk_enable() se llama en cada ciclo de PM (suspender/reanudar). - regulator_bulk_disable() nunca se llama. Por lo tanto, el recuento de referencias para estos reguladores aumenta constantemente, en uno con cada ciclo de bajo consumo, debido a la falta de la llamada a regulator_bulk_disable() en __dwc2_lowlevel_hw_disable(). La correcci\u00f3n original, que introdujo la llamada a devm_add_action_or_reset(), solucion\u00f3 un problema durante el sondeo que se produce debido a otros errores en dwc2_driver_probe() -> dwc2_core_reset(). En ese caso, el sondeo falla sin deshabilitar los reguladores cuando dr_mode == USB_DR_MODE_PERIPHERAL. Mejor soluci\u00f3n: deshabilite todo el hardware de bajo nivel en la ruta de error mediante el indicador \"hsotg->ll_hw_enabled\".
