From ef9d884dadd4c9f2c8432a6b82309ae4a133a35d Mon Sep 17 00:00:00 2001 From: "tom.leiming@gmail.com" Date: Mon, 11 Jun 2012 15:19:39 +0000 Subject: [PATCH] usbnet: remove usb_get/put_dev in .probe and .disconnect 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. Signed-off-by: Ming Lei Signed-off-by: David S.
