[PATCH 3/3] soc: fsl: make guts driver explicitly non-modular

From: Paul Gortmaker
Date: Sun Nov 13 2016 - 17:20:06 EST


The Kconfig currently controlling compilation of this code is:

drivers/soc/fsl/Kconfig:config FSL_GUTS
drivers/soc/fsl/Kconfig: bool

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

Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.

We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.

Since the code was already not using module_init, the init ordering
remains unchanged with this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
