	                            LiFi.

	                                                         interface.

i.e., I think that this needs:

	depends on PURELIFI

	                            LiFi as an Access Point.
or
	                            LiFi in Access Point mode.
or make something up. :)

	                                                         interface.

Same module, not a separate one, right?

Why does this check for CONFIG_PURELIFI_AP=m ?
How about if CONFIG_PURELIFI_AP=y ?

It would be more common just to check for CONFIG_PURELIFI_AP in the source
file(s) instead of adding a synonym for it.
