Subject: [PATCH] Bluetooth: HCI: Add proper tracking for enable status of adv instances
Date: Mon, 28 Jun 2021 17:49:52 -0700 [thread overview]
Message-ID: <20210629004952.569862-1-luiz.dentz@gmail.com> (raw)
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
This adds a field to track if advertising instances are enabled or not
and only clear HCI_LE_ADV flag if there is no instance left advertising.
