We usually open() device node obtained by sd_device_get_devname(). However, the device node corresponds to the sd-device object may be already removed, and another device node with the same path may be created, hence an unexpected device may be opened. The sd_device_open() opens device node, and checks the devnum and diskseq of opened devnum, to avoid the above possibility.
