Subject: [PATCHv3 07/10] Bluetooth: hci_serdev: do not open device in hci open
Date: Tue, 28 Mar 2017 17:59:36 +0200 [thread overview]
Message-ID: <20170328155939.31566-8-sre@kernel.org> (raw)
In-Reply-To: <20170328155939.31566-1-sre@kernel.org>
The device driver may need to communicate with the UART
device while the Bluetooth device is closed (e.g. due
to interrupts).
