[PATCH 00/24] ASoC: codecs: Use guard() for mutex & spin locks

[phucduc.bui]

From: bui duc phuc <phucduc.bui@gmail.com>

Hi all,

This series converts mutex and spinlock handling in ASoC codec drivers
to use the guard() and scoped_guard() helpers.

This series is split out from a larger 78-patch series to improve
reviewability and allow for incremental review:
https://lore.kernel.org/all/20260617103235.449609-1-phucduc.bui@gmail.com/

The changes are purely refactoring and have no functional impact.

Compile-tested only.

Best regards,
Phuc

[PATCH 13/24] ASoC: codecs: cs35l56: Use guard() and PM runtime scope helpers

[phucduc.bui]

From: bui duc phuc <phucduc.bui@gmail.com>

Convert the interrupt handler to use guard(mutex) for automatic mutex
unlocking and PM_RUNTIME_ACQUIRE_IF_ENABLED() to manage the runtime PM
reference through scope-based cleanup.
This removes the explicit cleanup paths while preserving the existing
behavior.

[PATCH 15/24] ASoC: codecs: cs42l43: Use guard() and PM runtime scope helpers

Convert mutex locking to guard(mutex) and replace explicit runtime
PM handling with runtime PM scope helpers.
This simplifies the control flow by removing explicit cleanup paths
and unnecessary 'goto' labels.

Thanks for the review.

Guards are particularly nice when they can eliminate goto labels and
make the code easier to follow.
In this file, as you pointed out, they don't make much difference.
Even so, I wanted to keep the style consistent across the driver,
so I tried to convert as many suitable cases as possible.

Best regards,
Phuc

I really don't like this duplicating of code blocks, it takes us
to a situation we always need to remember to update both blocks
in sync which feels like it makes reviewing future patches very
error prone.

Like cs42l43 I am really not sure about this duplicated code
block.

We can just drop this second write, update_bits won't do a
write if the bits don't change and we know they won't from the
read earlier. The original code was a bit odd, but might as well
clean it up whilst we are shuffling this all around.

Charles

Hi Charles,

I understand your concern about duplicating the code.

My reasoning is that duplicating this block once lets us eliminate 12
`goto` labels,
which I think makes the overall flow easier to follow. To me, that's a
reasonable trade-off.

If you have a cleaner approach that avoids both the duplicated block
and the 12 `goto` labels,
I'd be happy to adopt it.

Best regards,
Phuc
