Subject: [PATCH 2/2] Bluetooth: Store supported commands only during setup procedure
Date: Thu, 31 Oct 2013 04:54:33 -0700 [thread overview]
Message-ID: <1383220473-33584-2-git-send-email-marcel@holtmann.org> (raw)
The list of supported commands of a controller can not change during
its lifetime. So store the list just once during the setup procedure
and not every time the HCI command is executed.
