From 04130cc973a96df33b1429024fd6dec59fa35a84 Mon Sep 17 00:00:00 2001 From: Daniel Tang Date: Sun, 9 Jun 2013 12:33:55 +1000 Subject: Fix a build warning in scripts/mod/file2alias.c On some systems, __used is already defined in sys/cdefs.h and causes a build warning: scripts/mod/file2alias.c:85:1: warning: "__used" redefined In file included from /usr/include/stdio.h:64, from scripts/mod/modpost.h:1, from scripts/mod/file2alias.c:13: /usr/include/sys/cdefs.h:146:1: warning: this is the location of the previous definition This adds an extra check before defining the __used macro to see if the macro was already defined elsewhere.

The RapidIO modalias string format is shown below: "rapidio:vNNNNdNNNNavNNNNadNNNN" Where: v - Device Vendor ID (16 bit), d - Device ID (16 bit), av - Assembly Vendor ID (16 bit), ad - Assembly ID (16 bit), as they are reported in corresponding Capability Registers (CARs) of each RapidIO device.
