This is handled at the end of the function; if bad_config is set, it will return -1. (and bad_config is cleared by default in config==FUNCMUX_DEFAULT, and FUNCMUX_SDMMC1_SDIO1_4BIT==FUNCMUX_DEFAULT)

SDMMC1 is the module name, and SDIO1 is the pingroup name it's being routed to. I'm not sure what the inconsistency is. I don't recall if SDMMC1 can be routed to different pingroups or not.
