From d67dec5b2cc208215de21dc7806945bf6a6e85d0 Mon Sep 17 00:00:00 2001 From: Márton Németh Date: Sun, 10 Jan 2010 17:59:22 +0100 Subject: HID: make USB device id constant MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The id_table field of the struct usb_device_id is constant in so it is worth to make the initialization data also constant.
