[PATCH 0/3] leds/pwm: don't call pwm_disable when setting brightness

[Uwe Kleine-König]

Hello,

some time ago I pointed out a problem with leds-pwm on i.MX28, because
on this SoC it can happen that after:

	pwm_config(pwm, 0, period);
	pwm_disable(pwm);

the connected LED stays on. The mail thread is available at

	http://thread.gmane.org/gmane.linux.kernel/1381289

This series implements the outcome that didn't get any opposition, i.e.
the pin state is explicitly undefined after pwm_disable. The first patch
adds this fact to the general pwm docs, the second patch fixes the
leds-pwm driver accordingly. The third patch is just a trivial fix that
I noticed while patching the leds-pwm driver and not really related to
any problem.

Best regards
Uwe
