But in order to boot the firmware on resume, we need to reset the device. And if system suspend has been cancelled before mmc_power_off() was invoked, we will not be able to. So, in this case too, the driver will have to power the device off. It all really boils down to the same solution - we will always have to bypass runtime PM and directly control the power of the device. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
