Subject: [PATCH] scripts/gdb: Fix lx-device-list-bus and lx-device-list-class
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.
Fixes: 83b9148df2c9 ("driver core: bus: bus iterator cleanups")
Fixes: 7b884b7f24b4 ("driver core: class.c: convert to only use class_to_subsys")
