[PATCH 1/3] ofpathname: Add partition support to l2of_ide() and l2of_scsi()
Currently, only l2of_nvme() supports handling of partitions which
will print the partition number at the end of an OF path. However,
this feature is also useful for IDE and SCSI targets as well and
mandatory for Macintosh systems.
