[PATCH 04/22] mfd: da903x: Make it explicitly non-modular

From: Paul Gortmaker
Date: Sun Dec 02 2018 - 23:25:07 EST


The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config PMIC_DA903X
drivers/mfd/Kconfig- bool "Dialog Semiconductor DA9030/DA9034 PMIC Support"

...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 module_init was not in use by this code, the init ordering
remains unchanged with this commit.

We replace module.h with init.h and export.h ; the latter since this
file does export some syms.

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

We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
