If anyone has any objections, please let me know. ------------------ From: Florian Fainelli [ Upstream commit 801a2b1b49f4dcf06703130922806e9c639c2ca8 ] After the conversion to bus_to_subsys() and class_to_subsys(), the gdb scripts listing the system buses and classes respectively was broken, fix those by returning the subsys_priv pointer and have the various caller de-reference either the 'bus' or 'class' structure members accordingly.
