Subject: [PATCH 09/18] mfd: twl4030-power: Make it explicitly non-modular
Date: Wed, 18 Dec 2019 15:48:48 -0500	[thread overview]
Message-ID: <1576702137-25905-10-git-send-email-paul.gortmaker@windriver.com> (raw)
In-Reply-To: <1576702137-25905-1-git-send-email-paul.gortmaker@windriver.com>

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.
