[PATCH] mmc: sdhci: use IS_REACHABLE(CONFIG_LEDS_CLASS) to enable LED code
From: Masahiro Yamada
Date: Wed Apr 13 2016 - 04:55:14 EST
defined(CONFIG_LEDS_CLASS) || (defined(CONFIG_LEDS_CLASS_MODULE) && \
defined(CONFIG_MMC_SDHCI_MODULE))
is equivalent to:
defined(CONFIG_LEDS_CLASS) || (defined(CONFIG_LEDS_CLASS_MODULE) && \
defined(MODULE))
and it can also be written shortly as:
IS_REACHABLE(CONFIG_LEDS_CLASS)
