[PATCH 45/54] kobject: convert s390 ipl.c to kobj_attr interface

[Greg Kroah-Hartman <gregkh@suse.de>]

This makes the code a bit simpler and and gets us one step closer to
deleting the deprecated subsys_attr code.

NOTE, this needs the next patch in the series in order to work properly.
This will build, but the sysfs files will not properly operate.
