rewrite Get Device ID using new provider API
Modify to use the new provider API. One by one, change calls to remove any legacy API constructs. Tested-by: ipmitool raw 6 1 check for expected output Change-Id: I59688627eb32670559c1defad0b7af8abeb84c75 Signed-off-by: Vernon Mauery <vernon.mauery@linux.intel.com>
