From 7d40d7e85a25e01948bcb4dc3eda1355af318337 Mon Sep 17 00:00:00 2001 From: Németh Márton Date: Sun, 10 Jan 2010 15:34:24 +0100 Subject: USB serial: 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.
