[PATCH v3 00/27] ASoC: codecs: Use guard() for mutex & spin locks - part 2

[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 is part 2 of a larger 78-patch conversion series. Part 1 (24
patches) has already been posted, while this series contains the next
27 patches to keep the review manageable.

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.

Changes in v3:
 - Rebased onto the latest broonie/for-next.

Changes in v2: 
 - Add Reviewed-by tags from Charles and Herve.
 - Address Herve's review comments.

Link v2: 
https://lore.kernel.org/all/20260708141734.578926-1-phucduc.bui@gmail.com/
Link v1 :

Hi Mark,

Sorry for the confusion.

I've hit my email sending limit. I will send the remaining 25 parts
after 24 hours
to ensure they all go through.

This function does also have some goto based unwinding, there's a
similar thing in the rt721 changes.

Hi Mark,

Thanks for the review.

It seems this goto block was added recently, and I missed it after rebasing.
Sorry for the inconvenience.
However, looking at the goto path, it seems we might need to unwind the
states more completely. What do you think about rewriting it like this?

------------------
regcache_cache_only(rt712->regmap, false);
    ret = regcache_sync(rt712->regmap);
    if (ret) {
        regcache_cache_only(rt712->regmap, true);
        regcache_mark_dirty(rt712->regmap);
        return ret;
    }

    regcache_cache_only(rt712->mbq_regmap, false);
    ret = regcache_sync(rt712->mbq_regmap);
    if (ret) {
        regcache_cache_only(rt712->regmap, true);
        regcache_cache_only(rt712->mbq_regmap, true);
        regcache_mark_dirty(rt712->mbq_regmap);
        return ret;
    }

    return 0;
--------------------


Best regards,
Phuc

Since regmap was already synced successfully, marking it dirty again
would be redundant and could cause the next regcache_sync() to
needlessly rewrite cached registers that are already known to be in sync.

Also, in my understanding, any register write that happens afterwards
while cache_only=true should automatically set cache_dirty=true again
(see _regmap_write(), _regmap_raw_write_impl(),
regmap_noinc_readwrite(), and _regmap_multi_reg_write() in regmap.c),
so there may be no need to defensively mark it dirty here in case of
a later write. Reads aren't a concern here, since a read never
changes any state - it's only writes that can make the cache diverge
from the hardware while cache_only is set.
 Please correct me if I'm missing something here.
Best regards,
Phuc
