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)

I recently sent a change to the LEDS code:

	http://marc.info/?l=linux-mmc&m=146046055330711

So, if that is accepted, this will need to be changed - there will be only
one place CONFIG_LEDS_CLASS is used then.
