Subject[PATCH 04/16] staging: gasket: core: remove kobj_name param from gasket_alloc_dev
Date
From: Todd Poynor <toddpoynor@google.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.
