The regulator_lock_two() function could be made clearer in the case of
lock contention by having a local variable for each of the held and
contended locks. Let's do that. At the same time, let's use the swap()
function instead of open coding it.

This change is expected to be a no-op and simply improves code

Follow-up for my initial patch regarding the disabling of unused
voltage monitors. We use the PWR_OK functionality, which asserts GP_FB2
if every monitored voltage is in range. This patch should provide the
possibility to deactivate a voltage monitor from the DT if the regulator
might be disabled during run time. For this purpose, the regulator
notification support is used:

drivers/regulator/stm32-pwr.c:166 stm32_pwr_regulator_probe() warn:
'base' from of_iomap() not released on lines: 151,166.

In stm32_pwr_regulator_probe(), base is not released
when devm_kzalloc() fails to allocate memory or
devm_regulator_register() fails to register a new regulator device,
which may cause a leak.

To fix this issue, replace of_iomap() with
devm_platform_ioremap_resource(). devm_platform_ioremap_resource()
is a specialized function for platform devices.
It allows 'base' to be automatically released whether the probe
function succeeds or fails.

Besides, use IS_ERR(base) instead of !base
as the return value of devm_platform_ioremap_resource()
can either be a pointer to the remapped memory or
an ERR_PTR() encoded error code if the operation fails.

The problem was first reported soon after we made many of the
regulators probe asynchronously, though nothing I've seen implies that
the problems couldn't have also happened even without that.

I haven't personally been able to reproduce the lockdep issue, but the
issue does look somewhat legitimate. Specifically, it looks like in
regulator_resolve_supply() we are holding a "rdev" lock while calling
set_supply() -> create_regulator() which grabs the lock of a
_different_ "rdev" (the one for our supply). This is not necessarily
safe from a lockdep perspective since there is no documented ordering
between these two locks.

In reality, we should always be locking a regulator before the
supplying regulator, so I don't expect there to be any real deadlocks
in practice. However, the regulator framework in general doesn't
express this to lockdep.

Let's fix the issue by simply grabbing the two locks involved in the
same way we grab multiple locks elsewhere in the regulator framework:
using the "wound/wait" mechanisms.

When a codepath locks a rdev using ww_mutex_lock_slow() directly then
that codepath is responsible for incrementing the "ref_cnt" and also
setting the "mutex_owner" to "current".

The regulator core consistently got that right for "ref_cnt" but
didn't always get it right for "mutex_owner". Let's fix this.

It's unlikely that this truly matters because the "mutex_owner" is
only needed if we're going to do subsequent locking of the same
rdev. However, even though it's not truly needed it seems less
surprising if we consistently set "mutex_owner" properly.

The runtime suspend/resume functions are only referenced from the
dev_pm_ops, but they use the old SET_RUNTIME_PM_OPS() helper that
requires a __maybe_unused annotation to avoid a warning:

  drivers/media/i2c/imx290.c:1082:12: error: unused function 'imx290_runtime_resume' [-Werror,-Wunused-function]
  static int imx290_runtime_resume(struct device *dev)
             ^
  drivers/media/i2c/imx290.c:1090:12: error: unused function 'imx290_runtime_suspend' [-Werror,-Wunused-function]
  static int imx290_runtime_suspend(struct device *dev)
             ^

Convert this to the new RUNTIME_PM_OPS() helper that so this is not
required.  To improve this further, also use the pm_ptr() helper that
lets the dev_pm_ops get dropped entirely when CONFIG_PM is disabled.

A related mistake happened in the of_match_ptr() macro here, which like
SET_RUNTIME_PM_OPS() requires the match table to be marked as
__maybe_unused, though I could not reproduce building this without
CONFIG_OF.  Remove the of_match_ptr() here as there is no point in
dropping the match table in configurations without CONFIG_OF.
