[PATCH] ASoC: qcom: lpass-sc7180: Add maybe_unused tag for system PM ops

[Srinivasa Rao Mandadapu]

Add __maybe_unused tag for system PM ops suspend and resume.
This is required to fix allmodconfig compilation issue.
Fixes: c3bf7699747c ("ASoC: qcom: lpass-sc7280: Add system suspend/resume PM ops")

Thanks!

[1/1] ASoC: qcom: lpass-sc7180: Add maybe_unused tag for system PM ops
      commit: e8679db2970f04ee5281c042977fff880a3c045a

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

A better solution would be replacing SET_SYSTEM_SLEEP_PM_OPS() with
SYSTEM_SLEEP_PM_OPS(), which was added to avoid needing to add these
'__maybe_unused' attributes to these functions. See commit 1a3c7bb08826
("PM: core: Add new *_PM_OPS macros, deprecate old ones") for more info.

Tried this option but as this patch required for Kernel 5.4 version code 
base,

SYSTEM_SLEEP_PM_OPS didn't work.

Ah right, it is a more recent macro. I did not realize this patch was
needed to fix a patch destined for stable.

Perhaps keep this patch but add a second patch after it that converts
to using SYSTEM_SLEEP_PM_OPS() for future releases?

Older downstream trees needing a change shouldn't impact how a change is done
upstream. The change should be what's best for the upstream kernel. Downstream
kernels can do backports which might differ from the upstream solution or
pick the missing dependencies (which might not be too hard in this case).

This is incorrect, it should be '2d68148f8f85 ("ASoC: qcom: lpass-sc7180: Add
system suspend/resume PM ops")'. I see you fixed that in v2, but this patch
has already been applied ...

Srinivasa, it seems a similar patch is needed for commit c3bf7699747c ("ASoC:
qcom: lpass-sc7280: Add system suspend/resume PM ops"). For that you could use
SYSTEM_SLEEP_PM_OPS() instead of the maybe_unused tags as suggested by Nathan.

Mark, I appreciate you being responsive and picking patches quickly, it might
help though to leave 'external' reviewers at least some time to provide their
feedback :)

There's a balance with hanging on for utterly trivial patches to get
reviewed, especially in areas where reviews aren't relaible or
consistent.

The tag of the applied patch is incorrect too, which is actually what I noticed:

Fixes: a3a96e93cc88 ("ASoC: qcom: lpass-sc7280: Add system suspend/resume PM ops")

This patch is for sc7180, so it should be:

Fixes: 2d68148f8f85 ("ASoC: qcom: lpass-sc7180: Add system suspend/resume PM ops")

I understand it's a balance and I certainly can't claim to be a regular reviewer
of audio patches.

Oh, well.  It's just a fixes tag for something that has only been in
