[PATCH 0/4] reset: de-modularize the remaining reset drivers

[Paul Gortmaker]

Recently, a new reset driver was added that used module stuff in a
driver that was clearly non-modular[1].  With that in mind, it is
probably wise to get the remaining patches I have locally for the
existing reset drivers out the door, so we don't get any more
future instances of a new driver copying the old error once again.

Paul.

[PATCH 3/4] reset: meson: make it explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

arch/arm/mach-meson/Kconfig:menuconfig ARCH_MESON
arch/arm/mach-meson/Kconfig:    bool "Amlogic Meson SoCs"

arch/arm64/Kconfig.platforms:config ARCH_MESON
arch/arm64/Kconfig.platforms:   bool "Amlogic Platforms"

...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.

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
was (or is now) contained at the top of the file in the comments.

Applied, much appreciated.
I'll wait a bit for the remaining authors' Acked-by:s and then push them
out.
