CVE-2026-80643: EDAC/igen6: Fix call trace due to missing release()

Q: When does this issue occur?

The warning occurs when the igen6_edac driver is unloaded. The affected cleanup path unregisters memory controller devices that lack a release() function.

Q: What is required to trigger the call trace?

An attacker is not described in the available information. Triggering the reported condition requires unloading the igen6_edac kernel driver, such as through rmmod.

Q: What mitigation is available if an update cannot be applied immediately?

Avoid unloading the igen6_edac driver. The provided fix adds empty release() functions for its memory controller devices, preventing the device-release warning during driver removal.
