From: Oliver Neukum <oliver@...kum.org>
To: jgarzik@...ox.com
Cc: netdev@...r.kernel.org, USB list <linux-usb@...r.kernel.org>
Subject: [patch]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.
Signed-off-by: Oliver Neukum <oneukum@...e.de>
Hi Jeff,
we are doing this subsequently to all USB drivers. Please
apply. The patch is a simple search and replace operation.
Regards
Oliver
