[PATCH 09/18] mfd: twl4030-power: Make it explicitly non-modular

From: Paul Gortmaker
Date: Wed Dec 18 2019 - 15:49:19 EST


The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config TWL4030_POWER
drivers/mfd/Kconfig: bool "TI TWL4030 power resources"

...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. The remove function here was clearly a
no-op anyway, so no unbind functionality could possibly be impacted.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

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.
