[dm-devel] [PATCH 47/54] libmultipath: get_refwwid(): use find_path_by_devt()

[mwilck at suse.com]

From: Martin Wilck <mwilck at suse.com>

If get_refwwid is called with a dev_t argument, there's no point in converting
it into a devname first. If the device doesn't exist, get_udev_device() will fail.
