[RFC PATCH v2 4/6] mmc: Kconfig: downgrade CONFIG_MMC_DEBUG for host drivers only

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We have removed all code depending on CONFIG_MMC_DEBUG
from mmc core now. So it's safe to make CONFIG_MMC_DEBUG
just for host drivers only and we expect to kill this option
in the future.
