La implementaci\u00f3n revid de Qualcomm SPMI PMIC est\u00e1 rota de varias maneras.

En segundo lugar, accede a los datos del controlador de un dispositivo hermano directamente y sin ning\u00fan bloqueo, lo que significa que los datos del controlador pueden liberarse mientras se accede a ellos (por ejemplo, al desvincular el controlador).
