Subject: [PATCH 2/7] usbnet:pegasus: remove usb_get/put_dev in .probe and .disconnect
Date: Tue, 12 Jun 2012 09:19:40 +0800 [thread overview]
Message-ID: <1339463985-9006-3-git-send-email-tom.leiming@gmail.com> (raw)
In-Reply-To: <1339463985-9006-1-git-send-email-tom.leiming-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
usb_device is parent device of usb_interface in the view of driver
model, so its reference count is always held during .probe/.disconnect
of usb_interface instance.
This patch just removes the unnecessay usb_get/put_dev.
