[PATCH v3 00/12] ASoC: mediatek: mt8189: Improve error handling

[phucduc.bui@gmail.com]

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

Hi all,

This series addresses part of the error handling in the MT8189 AFE driver.

It propagates errors from clock operations and runtime resume, validates
clock parameters, and removes redundant error messages.

In v2, there was discussion about checking the return value of 
regmap_update_bits(). While opinions differed, the existing driver already 
checks it in mt8189_afe_enable_top_cg(), which is used by 
mt8189_apll1_enable() and mt8189_apll2_enable() touched by this series.

Therefore, I keep these checks and add the corresponding error paths for 
consistency.

Compile-tested only.

Link v2:
https://lore.kernel.org/all/20260914072842.24420-1-phucduc.bui@gmail.com/

Changes in v2:
 - Update the names of the goto labels.
 - Check for zero frequency since freq is unsigned. 
Changes in v3:
 - Add Angelo's Reviewed-by tag.
 - Restore the existing afe->regmap checks, 
   making the separate patch for missing regmap unnecessary.
 - Do not pre-initialize ret; set ret = 0 in the default case throughout 
   the series.

Best regards,
Phuc
