[PATCH 00/10] clk: fix/remove module usage in non-modular code

[Paul Gortmaker]

This series covers the audit of non-modular module code use in the
drivers/clk/ directory.

Quasi generic boiler plate description follows; included for folks who
haven't yet seen what we are aiming to achieve with this operation.

We are trying to not use module support for code that can never be built
as a module because:

 (1) it is easy to accidentally write unused module_exit and remove code
 (2) it can be misleading when reading the source, thinking it can be
     modular when the Makefile and/or Kconfig prohibit it
 (3) it requires the include of the module.h header file which in turn
     includes nearly everything else, thus adding to CPP overhead.
 (4) it gets copied/replicated into other code and spreads like weeds.

With respect to #1 in this instance, we see for these 10 commits:
    15 files changed, 37 insertions(+), 227 deletions(-)
...which is a respectable (IMHO) net amount of removal of unused code.

Changes seen here cover the following categories:

  -just replacement of modular macros with their non-modular
   equivalents that CPP would have inserted anyway, such as:
	module_init --> device_initcall
	module_platform_driver --> builtin_platform_driver

  -the removal of including module.h ; replaced with init.h
   as required based on whether the file used it.

  -the removal of any/all unused/orphaned __exit functions that
   would never be called.

  -the removal of instances of MODULE_DEVICE_TABLE and MODULE_ALIAS
   that become no-ops in the non-modular case.

  -the removal of any ".remove" functions that were hooked into
   the driver struct.   This ".remove" function would of
   course not be called from the __exit function since that was
   never run.  However in theory, someone could have triggered it
   via sysfs unbind, even though there isn't a sensible use case
   for doing so.  So to cover that possibility, we've also disabled
   sysfs unbind in the driver.

  -the removal of MODULE_DESCRIIPTION/AUTHOR/LICENSE tags that are
   also no-ops for non-modular ; we ensure the information in those
   tags is present in the top of file comments in each case.

There are no initcall level changes here; everything stays at the level
of initcall it was previously - either by not using modular versions to
begin with, or by using the builtin level equivalents.

As usual, we can consider making some of these tristate if an author
has strong feelings about extending support into the modular realm,
but I won't be able to run-time test any of that.

I batched the sunxi changes together since they had similar author
and maintainer fields and it helps avoid polluting history with too
many mundane commits, but I can split that up if so desired.

Build testing done on linux-next on arm/arm64 and x86/x86_64.

Paul.

[PATCH 01/10] clk: meson8b: make it explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/clk/meson/Kconfig:config COMMON_CLK_MESON8B
drivers/clk/meson/Kconfig:      bool

...meaning that it currently is not being built as a module by anyone.
However a recent commit added a bunch of modular boilerplate to this
driver.

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_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

Also note that MODULE DEVICE_TABLE/ALIAS are no-op when non-modular.

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.

[PATCH 07/10] clk: samsung: make clk-s5pv210-audss explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

arch/arm/mach-s5pv210/Kconfig:config ARCH_S5PV210
arch/arm/mach-s5pv210/Kconfig:  bool "Samsung S5PV210/S5PC110" if ARCH_MULTI_V7

...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 this code is already not using module_init, case, the init
ordering remains unchanged with this commit.

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

[PATCH 08/10] clk: sunxi: make clk-* explicitly non-modular

[Paul Gortmaker]

We have the following file --> Kconfig mapping:

sunxi/clk-factors.c              obj-y
sunxi/clk-sun6i-apb0-gates.c     CONFIG_MFD_SUN6I_PRCM (bool)
sunxi/clk-sun6i-apb0.c           CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun6i-ar100.c          CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun8i-apb0.c           CONFIG_MFD_SUN6I_PRCM
sunxi/clk-sun9i-mmc.c            obj-y

Hence none of these are being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get mostly the same changes, so they are handled in batch.

Changes are (1) convert to builtin_platform_register, (2) use the
init.h header, (3) delete the MODULE_LICENCE/MODULE_AUTHOR and
associated tags, and (4) delete any ".remove" functions.

There was a stray module.h in a file not using any init.h or
module.h stuff, so we simply removed that one.

In two cases, 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_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

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

[PATCH 09/10] clk: tegra: make clk-tegra124-dfll-fcpu explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

arch/arm/mach-tegra/Kconfig:config ARCH_TEGRA_124_SOC
arch/arm/mach-tegra/Kconfig:    bool "Enable support for Tegra124 family"

...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_init translates to device_initcall in the non-modular
case, 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 tags etc. since all that information
is already contained at the top of the file in the comments.

Why not removing .remove() callback as well?

I don't find sysfs unbind hook useful except testing the exit paths...
which in that case do not exist anymore (there is no "modprobe -r" for
it anyway).

...which IMHO is largely a moot point, since the MODULE_<xyz> tags
aren't universally deployed and largely don't exist at all once you are
outside of the driver space.

Yes, I normally delete the .remove callbacks as indicated in the 0/10,
but somehow I overlooked this one.   Thanks for spotting it.  I'll
delete it and disable the sysfs bind in v2.

Thanks for the patch.  I will try to get rid of the above initcall 
instead of removing module support.  Any clock dependencies should 
now be handled properly with deferred probing.  And the module support 
will be useful since the audss clock controller is present only 
on selected Exynos SoC variants.

Applied to clk-next.

I know that we normally take PRs for the samsung clk stuff, but this
late in the cycle I'm OK to simply pick individual patches.

Thanks,
