* include/grub/util/getroot.h (grub_util_check_block_device): Export new
        function.
        * util/getroot.c (grub_util_check_block_device): New function that
        returns the given argument if it is a block device and returns NULL else.
        * util/grub-probe.c (argument_is_device): New variable.
        (probe): Promote device_name from a variable to an argument. Receive
        device_name from grub_util_check_block_device() if path is NULL and from
        grub_guess_root_device() else. Do not free() device_name anymore.
        (options): Introduce new parameter '-d, --device'.
        (main): Add description of the new parameter to the help screen.
        Rename path variable to argument. Set argument_is_device if the '-d'
        option is given. Pass argument to probe() depending on
        argument_is_device.
