Subject: [PATCH 04/16] staging: gasket: core: remove kobj_name param from gasket_alloc_dev

From: Todd Poynor <toddpoynor@...gle.com>

gasket_alloc_dev can retrieve the device name from the parent parameter,
a separate parameter isn't needed for this.  Rename the variable to
better reflect its meaning, as the name of the parent device for which a
gasket device is being allocated.
