Hi Jerome,

Thank you for the review and for the Reviewed-by tag.

Regarding the point about whether the change makes the code better or worse,
I have sent an additional patch to address related cleanup in the same area:

Would appreciate your review on that as well.

While looking into the Meson ASoC probe paths,
I noticed a few consistency issues that seem to appear across multiple drivers:

1. Mixed usage of dev_err_probe() and dev_err() in probe error paths.

2. Inconsistent error message formatting: some messages start with lowercase
   ("failed to init..."), while others start with uppercase ("Failed
to register...").

3. In aiu_probe(), error paths for IRQ retrieval do not provide
additional context,
    making it harder to identify which resource failed:

   aiu->i2s.irq = platform_get_irq_byname(pdev, "i2s");
   if (aiu->i2s.irq < 0)
           return aiu->i2s.irq;

   aiu->spdif.irq = platform_get_irq_byname(pdev, "spdif");
   if (aiu->spdif.irq < 0)
           return aiu->spdif.irq;

4 ......

Do you think addressing these issues would improve readability and
maintainability of the Meson codebase over time?
Or is it generally preferred to leave these kinds of consistency
improvements untouched unless a functional bug is being fixed?

Best regards,
Phuc
