CVE-2026-72259

The MT8192 AFE probe calls of_reserved_mem_device_init() and falls back to preallocated buffers when no reserved memory region is available. When the reserved memory assignment succeeds, however, the driver never releases it.

Register a devm cleanup action after a successful reserved-memory assignment so the assignment is released on probe failure and driver unbind.
