[PATCH v5 5/9] of: fdt: Use IS_ENABLED(CONFIG_BLK_DEV_INITRD) instead of #ifdef

From: Geert Uytterhoeven
Date: Wed Aug 11 2021 - 04:52:07 EST


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.
