[PATCH v4 0/8] ASoC: mediatek: mt8186: Fix clock error handling

[phucduc.bui@gmail.com]

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

Hi all,

This series fixes several error handling issues in the mt8186 ASoC driver.

The patches mainly address failures during APLL/mux, clock, MCK, GPIO,
and regcache operations. In particular, they make sure that partial
failures are handled correctly and that resources are left in a
consistent state.

The series also removes redundant probe error messages where the errors
are already reported by the called functions.

The changes were found by manual code inspection and compile-tested only.

Link v1 : 
https://lore.kernel.org/all/20260820111253.97866-1-phucduc.bui@gmail.com/

Link v2: 
https://lore.kernel.org/all/20260821123021.41390-1-phucduc.bui@gmail.com/

Link v3:
https://lore.kernel.org/all/20260828091532.600047-1-phucduc.bui@gmail.com/

Changes in v2:
 - Update the cover letter.
 - Drop patch 5 from v1.
 - Add Fixes tags.
Changes in v3:
 - Add a patch to fix clock handling in the mux disable path
 - Return directly from apllx_mux_setting() instead of using a goto label
 - Add GPIO rollback handling for partial failures in ADDA DL/UL.
 - Add Handle failures from regcache_sync().
 - Add a patch to remove redundant error messages from the probe path.
 - Update the cover letter.
Changes in v4:
 - In the mux disable path, remove the goto labels so that all teardown
   steps are attempted and any errors are only reported.

Best regards,
Phuc
