Subject: Re: [PATCH v23 02/16] leds: multicolor: Introduce a multicolor class
 definition

Dan,

I've converted drivers/leds/leds-an30259a.c to LED mc framework
and tested it on Samsung Galaxy S3 (exysnos4412-trats2 board).
Works as expected. And now the framework usability is indeed neater.

One thing to improve: LED mc based drivers' entries in Kconfig should 
have this dependency:

depends on LEDS_CLASS_MULTI_COLOR || !LEDS_CLASS_MULTI_COLOR

It is required to enforce building driver as a module if
LED mc framework is configured as such.

With this (and DT bindings nits) addressed, for patches 1-6:

Acked-by: Jacek Anaszewski <jacek.anaszewski@...il.com>

It's been a long journey. Thank you for your determination to drive
this work to the end.

Best regards,
Jacek Anaszewski
