Subject: [PATCH] leds: fix unsigned value overflow in for loop
Date: Tue, 13 May 2008 14:56:56 +0800 [thread overview]
Message-ID: <48293BB8.5090206@cn.fujitsu.com> (raw)
Fix the following unsigned variable overflow:
unsigned i;
for (i = n; i >= 0; i--)
...
It won't break anything to use type 'int'.
