[PATCH 00/11] ASoC: codecs: Mark expected switch fall-throughs

[Gustavo A. R. Silva]

Hi all,

In preparation to enabling -Wimplicit-fallthrough, this patchset aims
to add some annotations in order to mark switch cases where we are
expecting to fall through.

Thanks

The patch

   ASoC: wm8961: Mark expected switch fall-through

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

The patch

   ASoC: wm8996: Mark expected switch fall-through

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Wait, what? This looks like the sort of bug -Wimplicit-fallthrough is supposed
to catch.  Unless for 'case WM8994_SYSCLK_OPCLK:' we actually do want to do a
whole bunch of snd_soc_component_update_bits() calls and then return -EINVAL
whether or not that case succeeded?

Yeah, it seems like a bug. Can someone confirm this?

Notice that this code has been there since 2010.

Basically nobody ever uses OPCLK so I'd be susprised if anyone ever
noticed.

I see. I wonder what's the best approach in this case. Should that code be removed instead of 'fixed'?

I wonder if nobody uses it because any attempts to do so get an error? :)

I'm thinking that's a spot that needs a 'break;' added.

Of course, my understanding of that code is limited to looking at the first 10
patches and the fall-through hit something reasonable, and then the last
one did a fall-through to an error return.

Yep. And I think the patch to fix this should be tagged for stable.

So, it seems we have two options:

1. Revert commit 2cea1542859bc812f1ec51ea71c06e927e5b922e and then apply a fix with the break statement.

or

2. Apply a fix with the break statement and then backport the fix to stable.

am I correct?

No, nobody ever physically wires up an OPCLK.  If one was there it'd be
unavoidable.
