Subject: [PATCH v4 6/7] leds: leds-pwm: Simplify cleanup code
Date: Wed, 12 Dec 2012 10:04:51 +0100 [thread overview]
Message-ID: <1355303092-15523-7-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1355303092-15523-1-git-send-email-peter.ujfalusi-l0cyMroinI0@public.gmane.org>
The code looks more nicer if we use:
while (i--)
instead:
if (i > 0)
for (i = i - 1; i >= 0; i--)
