Subject: [PATCH v3 4/5] Bluetooth: ISO: Use sk_sndtimeo as conn_timeout
Date: Wed, 13 Aug 2025 17:15:10 -0400 [thread overview]
Message-ID: <20250813211511.90866-4-luiz.dentz@gmail.com> (raw)
In-Reply-To: <20250813211511.90866-1-luiz.dentz@gmail.com>
From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
This aligns the usage of socket sk_sndtimeo as conn_timeout when
initiating a connection and then use it when scheduling the
resulting HCI command, similar to what has been done in bf98feea5b65
("Bluetooth: hci_conn: Always use sk_timeo as conn_timeout").
