[PATCH 00/11] mfd: simple demodularization of non-modular drivers

[PATCH 00/11] mfd: simple demodularization of non-modular drivers

[Paul Gortmaker]

This group of MFD drivers are all controlled by "bool" Kconfig settings,
but contain traces of module infrastructure like unused/orphaned __exit
functions, use of <linux/module.h> and/or MODULE_ macros that are no-ops
in the non-modular case.

We can remove/replace all of the above.  We are trying to make driver
code consistent with the Makefiles/Kconfigs that control them.  This
means not using modular functions/macros for drivers that can never be
built as a module.  Some of the downfalls this leads to are:

 (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 drivers and spreads quickly.

The changes here should represent zero runtime changes.  Only the ones
with removed __exit functions will have a slightly smaller object size.
The source gets a net reduction of 100+ lines of unused code.

Build testing was done on drivers/mfd for allyesconfig on x86_64, ARM
and ARM-64.

Paul.

[PATCH 01/11] mfd: as3711: Make it explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_AS3711
drivers/mfd/Kconfig:    bool "AMS AS3711"

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

We don't replace module.h with init.h since the file already has that.

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.

[PATCH 02/11] mfd: da9055-core: make it explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_DA9055
drivers/mfd/Kconfig:    bool "Dialog Semiconductor DA9055 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.

The exit function deleted here wasn't even registered with module_exit,
so it truly was dead 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.

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

[PATCH 04/11] mfd: htc-i2cpld: Make it explicitly non-modular

[Paul Gortmaker]

The Kconfig for this option is currently:

config HTC_I2CPLD
        bool "HTC I2C PLD chip 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.

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

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

[PATCH 10/11] mfd: wm831x-core: drop unused MODULE_ tags from non-modular code

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_WM831X
drivers/mfd/Kconfig:    bool

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.

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

[PATCH 11/11] mfd: wm8400-core: Make it explicitly non-modular

[Paul Gortmaker]

The Kconfig currently controlling compilation of this code is:

drivers/mfd/Kconfig:config MFD_WM8400
drivers/mfd/Kconfig:    bool "Wolfson Microelectronics WM8400"

...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 was not in use by this code, 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.

Finally a function is renamed to remove word "module" in order to
possibly remove any confusion.

Thanks for the report -- I'll look into what causes it, why my testing
didn't see it, and get an update to Lee as soon as possible.

OK, mystery solved.  I chose this smaller subset of MFD "simple" patches
from my pending queue of MFD patches - to create a reasonable sized
maintainer-friendly send, based on patches with zero runtime changes.

My other pending MFD patches have a trivial runtime behavior change;
deleting a ".remove" field/function - that will never be used for a
non-module case, but in theory could be (pointlessly) triggered by
forcing a driver unbind.  (see mainline 98b72b94def9 as an example)
Patches like this were left behind for a future send batch.

Unfortunately that allowed me to overlook the fact that patch #2 link
depended on the below ".remove" patch (not sent) to be applied 1st.

Lee, what would you like to have happen?  I can resend the queue with
this patch, or I can resend with #2 being temporarily deferred until
a future patch batch that has the below da9055-i2c in it, or ...

Whatever is easiest for you - let me know.

Paul.

Date: Sun, 6 Sep 2015 22:10:34 -0400
Subject: [PATCH] mfd: da9055-i2c: Make it explicitly non-modular

The Makefile/Kconfig currently controlling compilation of this code is:

drivers/mfd/Makefile:da9055-objs := da9055-core.o da9055-i2c.o
drivers/mfd/Makefile:obj-$(CONFIG_MFD_DA9055)   += da9055.o

...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.

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.

What about when .remove() is invoked during shutdown?

It is my understanding that .remove is not invoked during shutdown.

If we step outside of MFD and look at mainline commit 7aa8619a66aea5
("iommu/arm-smmu-v3: Implement shutdown method") -- you can see it adds
a shutdown that is just a wrapper around the remove function.

If shutdown called remove, then this commit would cause the remove
function to get called *twice* on a shutdown.

I also don't see any obvious coupling in drivers/base/platform.c - they
seem independent, but it is possible I've overlooked something?

Thanks,
Paul.

Just send them all.

I'm going to have to review them all at one time or another.
