Subject: [PATCH 02/11] hwsim: check pending_create_msg before replying
Date: Thu, 17 Dec 2020 11:36:02 -0800	[thread overview]
Message-ID: <20201217193611.1177006-2-prestwoj@gmail.com> (raw)
In-Reply-To: <20201217193611.1177006-1-prestwoj@gmail.com>

In the NEW_RADIO callback hwsim was assuming that DBus had no
yet replied to the Create() method. In some cases the NEW_RADIO
event fires before the actual callback which will respond to
DBus. This causes a crash in the create callback.
