From 1bd4f29d0af5b4b1c022d8fded14665dd5932905 Mon Sep 17 00:00:00 2001 From: Németh Márton Date: Sun, 10 Jan 2010 15:33:33 +0100 Subject: USB skeleton: 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.
