From 6e2dbd7387bc2381e08aa85d6d33bb2d2d140843 Mon Sep 17 00:00:00 2001
From: Kevin Cernekee <cernekee@gmail.com>
Date: Tue, 5 Jun 2012 15:05:19 -0700
Subject: [PATCH] MIPS: Convert __syscall_error() callers to use $a0 for
argument
Some callers passed the first argument in $v0, while others used $a0.
Change the callers to use $a0 consistently.
