[PATCH 0/6] mfd: audit and demodule drivers/mfd/ab* drivers

[Paul Gortmaker]

Nothing new here ; just another instance where we had modular remove
and exit functions -- but the Makefile/Kconfig limited the use case to
being always built-in; hence the code is useless and needs removing.

So we remove the dead code and the misleading hints of modularity from
these drivers, hoping that we manage to prevent some new drivers from
copying these same old mistakes into pending new drivers.

Paul.

[PATCH 5/6] mfd: ab8500: make sysctrl explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config AB8500_CORE
drivers/mfd/Kconfig:    bool "ST-Ericsson AB8500 Mixed Signal Power Management chip"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

We replace module.h with init.h and export.h -- the latter since the file
does make use of EXPORT_SYMBOL.

Applied the series with Linus' Ack.
