[PATCH 1/3] ASoC: mediatek: mt2701: Use devm_clk_get_optional() for audio_mrgif_pd

[phucduc.bui]

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

The audio_mrgif_pd clock is optional as some platforms may support the
BT path while others do not. Use devm_clk_get_optional() to reflect
this.

Propagate other errors to the caller.

[PATCH 2/3] ASoC: mediatek: mt2701: Use dev_err_probe() for error handling

[phucduc.bui]

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

Replace dev_err() with dev_err_probe() to prevent log spam when probe
returns -EPROBE_DEFER.

[PATCH 3/3] ASoC: mediatek: mt2701: Drop redundant probe error messages

[phucduc.bui]

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

The errors handled here are already reported by the called functions,
either directly or deeper in the call chain. Therefore, the additional
dev_err() calls are redundant and can be removed.

What does that mean? Did the functional path change?

This should be part of a mediatek-patch-series with a cover letter. 
Yeah, the mt6797 changes should be here too.

Hi Cezary,

Thank you for your review.

Previously, the code only returned an error for -EPROBE_DEFER and
ignored other errors.
After switching to devm_clk_get_optional(), all other errors are
propagated to the caller as well.

Regarding the functional path, I don't think it changes on platforms
where the clock is present.
The change only allows platforms without this optional clock to
continue probing.

Currently, the MediaTek ASoC drivers are split into multiple groups by SoC.
I am handling them one group at a time to make the review easier.

I will send each group once it is completed, rather than waiting for the entire
MediaTek cleanup, which would take quite a long time. A single series
covering all
MediaTek SoCs would also be very long and harder to follow,
especially if changes are requested during review.

I hope this approach works for you.

Best regards,
Phuc

Thanks for the explanations. I see only benefits from these changes.
