Hi all,

This series converts mutex and spinlock handling in Intel ASoC drivers
to use guard()/scoped_guard() helpers.

Most changes are straightforward conversions intended to simplify lock
handling and cleanup paths, with no intended functional changes.

The series has been compile-tested only.

Link v1:
https://lore.kernel.org/all/20260611115901.80438-1-phucduc.bui@xxxxxxxxx/

Link v2:
https://lore.kernel.org/all/20260618110649.227062-1-phucduc.bui@xxxxxxxxx/

Changes in v2:
- Reduce the series from 20 patches to 4 patches.
- Drop smaller conversions that did not provide clear benefits.

Changes in v3:
- Drop the scoped_guard() conversion for the function that still used
a goto-based cleanup path.
- Move the __free(kfree) conversion into a separate patch.

Best regards,
Phuc
