From c94cb314503a69492bf4455dce4f6d300cff0851 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Thu, 18 Dec 2008 23:00:59 -0800 Subject: [PATCH] net: prepare usb net drivers for addition of status as a parameter USB is going to switch the signature of the callbacks to void callback(struct urb *urb, int status) This patch will ease the transition.
