[PATCH v4 2/5] ASoC: mediatek: mt8183: Fix clock handling in mux disable path
From: <hidden>
Date: 2026-09-03 04:53:10

From: bui duc phuc <redacted>
In the disable path of the appl*_mux_setting() functions,
clk_disable_unprepare() is called after clk_set_parent().
If clk_set_parent() fails, clk_disable_unprepare() is skipped,
potentially leaving one of the clocks enabled.
Remove the goto exit paths so that all teardown steps are attempted
and any errors are only reported.

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.
