Subject: [PATCH v4 05/10] of: fdt: Use IS_ENABLED(CONFIG_BLK_DEV_INITRD) instead of #ifdef
Date:   Wed, 14 Jul 2021 14:50:15 +0200
Message-Id: <2f6ab7db7f9657b809aba7693df697c9bf9f57ae.1626266516.git.geert+renesas@glider.be>
In-Reply-To: <cover.1626266516.git.geert+renesas@glider.be>
References: <cover.1626266516.git.geert+renesas@glider.be>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

Replace the conditional compilation using "#ifdef CONFIG_BLK_DEV_INITRD"
by a check for "IS_ENABLED(CONFIG_BLK_DEV_INITRD)", to increase compile
coverage and to simplify the code.
