[PATCH v2 0/3] pinctrl: intel: Replace ifdeffery by pm_sleep_ptr() macro Andy Shevchenko

[Andy Shevchenko]

There are two benefits of this series:
1) no more ugly ifdeffery in the code;
2) the PM callbacks are all being synchronised via using the same macro,
i.e. pm_sleep_ptr() everywhere.

v2:
- made the code readable again (Mika)

Andy Shevchenko (3):
  pinctrl: intel: Replace ifdeffery by pm_sleep_ptr() macro
  pinctrl: baytrail: Replace ifdeffery by pm_sleep_ptr() macro
  pinctrl: cherryview: Replace ifdeffery by pm_sleep_ptr() macro

[PATCH v2 1/3] pinctrl: intel: Replace ifdeffery by pm_sleep_ptr() macro

[Andy Shevchenko]

Explicit ifdeffery is ugly and theoretically might be not synchronised
with the rest of functions that are assigned via pm_sleep_ptr() macro.
Replace ifdeffery by pm_sleep_ptr() macro to improve this.

No way, this looks even worse :(

Let's not do this change please.
