[PATCH v3 25/27] ASoC: codecs: rt712: Use guard() for mutex locks

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
