Subject: [PATCH 0/2] linux/kconfig.h: move IF_ENABLED() out of <linux/kconfig.h>


I insist on <linux/kconfig.h> having only minimal set of macros
that are needed to evaluate CONFIG options.

Everytime somebody added an alien to <linux/kconfig.h>, I needed to
kick it out.

I did not notice 1b399bb04837183cecdc1b32ef1cfc7fcfa75d32 because
I was not addressed by [1].

[1]: https://lore.kernel.org/lkml/?q=kconfig.h%3A+Add+IF_ENABLED%28%29+macro

I like Paul's idea, but if I had noticed the patch in time, I would
have tried my best to persuade to implement it outside of <linux/kconfig.h>
(Paul's initial patch was adding it to a new header instead of <linux/kconfig.h>)

Before it is widely used, I want to fix it.

In 2/2, I converted pm.h to allow driver cleanups.



Masahiro Yamada (2):
  linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in
    <linux/kernel.h>
  pm: allow drivers to drop #ifdef and __maybe_unused from pm callbacks
