[PATCH v2] dbus: Make P2P group properties accessible individually
Angie Chinchilla
angie.v.chinchilla
Wed Feb 29 14:42:48 PST 2012
From: Todd Previte <toddx.a.previte at intel.com>
Group properties are now accessible individually. The function to retrieve
the dictionary containing the group properties is removed in favor of the
individual functions. The group member properties are removed as well as
they erroneously retrieved the group properties via the old function.
