Subject: [PATCH v2 2/2] driver core: class: Correct WARN() message in APIs
 class_(for_each|find)_device()

From: Zijun Hu <quic_zijuhu@...cinc.com>

For both API class_for_each_device(const struct class *class, ...) and
class_find_device(const struct class *class, ...), their WARN() messages
prompt @class was not initialized when suffer class_to_subsys(@class)
error, but the error actually means @class was not registered, so these
warning messages are not accurate.

Fix by replacing term initialized with registered within these messages.
