Subject: [OSS-Tools] [PATCH dt-utils 11/13] state: harmonize code with barebox
Date: Mon, 30 Sep 2019 09:26:11 +0200
Message-ID: <20190930072613.17956-12-u.oelmann@pengutronix.de> (raw)
In-Reply-To: <20190930072613.17956-1-u.oelmann@pengutronix.de>

This ports the following barebox commit:

| commit cdbeddf62b7a01f09f00e0fe94430789f4b0b05e
| Author: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
| Date:   Wed Sep 11 21:27:38 2019 +0200
|
|     state: provide dummy implementations for some functions when STATE is
|     disabled
|
|     This allows to simplify some callers as can be seen from the
|     phytec-som-am335x/board.c change. (The check for state != NULL could be
|     dropped already before.)
