Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The aml sfc probe() function registers the on-host NAND ECC engine, but it lacks the necessary teardown process during probe unwind and remove-time cleanup. This results in the ECC engine not being unregistered when a probe failure occurs or when the device is removed.

Recommendations Implement a devm cleanup action after successful registration to ensure the nand ecc unregister on host hw engine() function runs automatically during probe failures and device removal.
