[PATCH 1/3] ASoC: mt6797: fix wrong unwind order and error code in enable_clock

[phucduc.bui@gmail.com]

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

The error paths in mt6797_afe_enable_clock() use incorrect goto labels,
causing clocks that failed to enable to be disabled during cleanup.

Fix the goto labels to only unwind clocks that were successfully
enabled, and return the actual error code.
