Subject: [RFC] Add inline routine to free memory used in kobject name

At present, if one wants to free the memory allocation used for
a dev->kobj name, it is necessary to go quite deeply into the structure.
To avoid this much dependence on the structure details in driver
code, a new inline routine is created.
