[PATCH v2] mux: remove the Kconfig question for the subsystem

From: Peter Rosin
Date: Tue Jul 04 2017 - 04:21:54 EST

The MULTIPLEXER question in the Kconfig might be confusing and is
of dubious value. Remove it. This makes consumers responsible for
selecting MULTIPLEXER, which they already do.

Right, the previous patch also had the problem that it removed
the MULTIPLEXER option completely and was therefore total crap.

I have tested this patch more thoroughly and it should be a
definite improvement. Sorry for the noise...

- Multiplexer controller subsystem. Multiplexers are used in a
- variety of settings, and this subsystem abstracts their use
- so that the rest of the kernel sees a common interface. When
- multiple parallel multiplexers are controlled by one single
- multiplexer controller, this subsystem also coordinates the
- multiplexer accesses.
- To compile the subsystem as a module, choose M here: the module will
