[PATCH 2/6] remoteproc: imx_rproc: Use devm_add_action_or_reset() for workqueue cleanup
Posted by Peng Fan 2 weeks ago
Replace manual destroy_workqueue() calls in error and remove paths with a
devm_add_action_or_reset() helper. Ensure the workqueue is properly
cleaned up with the device lifecycle, and simplify error handling in probe
by removing now-unnecessary labels and cleanup steps.

No functional changes.
