From 3e74341c7b356ce142ace4e9b5ff08448c9f320e Mon Sep 17 00:00:00 2001 From: Amol Lad Date: Tue, 17 Oct 2006 10:02:55 +0530 Subject: [CPUFREQ] sc520_freq.c: ioremap balanced with iounmap ioremap must be balanced by an iounmap and failing to do so can result in a memory leak. Tested (compilation only): - using allmodconfig - making sure the files are compiling without any warning/error due to new changes Signed-off-by: Amol Lad Signed-off-by: Dave Jones --- arch/i386/kernel/cpu/cpufreq/sc520_freq.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'arch/i386/kernel') diff --git a/arch/i386/kernel/cpu/cpufreq/sc520_freq.c b/arch/i386/kernel/cpu/cpufreq/sc520_freq.c index ef457d50f4a..b8fb4b521c6 100644 --- a/arch/i386/kernel/cpu/cpufreq/sc520_freq.c +++ b/arch/i386/kernel/cpu/cpufreq/sc520_freq.c @@ -153,6 +153,7 @@ static struct cpufreq_driver sc520_freq_driver = { static int __init sc520_freq_init(void) { struct cpuinfo_x86 *c = cpu_data; + int err; /* Test if we have the right hardware */ if(c->x86_vendor != X86_VENDOR_AMD || @@ -166,7 +167,11 @@ static int __init sc520_freq_init(void) return -ENOMEM; } - return cpufreq_register_driver(&sc520_freq_driver); + err = cpufreq_register_driver(&sc520_freq_driver); + if (err) + iounmap(cpuctl); + + return err; } -- cgit v1.2.3
