[PATCH 0/4] drivers: spi: st: use pm_ptr and remove __maybe_unused

[Alain Volmat]

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

Patch is fine, but reasoning not quite right. pm_ptr() allows
the dropping of the structure without needing a __maybe_unused
on that, but these are passed to the SYSTEM_SLEEP_PM_OPS()
macro and that is using pm_sleep_ptr().

So tiny description change needed to reflect that. Probably
mention the pm_sleep_ptr() is as part of the macro as that
bit is not totally obvious.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
