Subject: leds: leds-pwm: Simplify cleanup code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8a66a579083a20172a46e74d175a57621dccae0a;p=linux-beck.git

leds: leds-pwm: Simplify cleanup code

The code looks more nicer if we use:

while (i--)

instead:
if (i > 0)
	for (i = i - 1; i >= 0; i--)
