Subject: [PATCH 24/36] usb: serial: ti_usb_3410_5052: Use usb_serial_generic_open
Date: Thu, 12 May 2016 10:48:56 +0200	[thread overview]
Message-ID: <1463042948-12205-25-git-send-email-m.othacehe@gmail.com> (raw)
In-Reply-To: <1463042948-12205-1-git-send-email-m.othacehe@gmail.com>

Use usb_serial_generic_open in open callback to start read urb.
Also remove useless usb_device pointer.
