ASoC: mediatek: mt8183: Release reserved memory on cleanup
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: mt8183: Release reserved memory on cleanup The MT8183 AFE probe can assign reserved memory with of_reserved_mem_device_init(), but the assignment is never released on driver removal or later probe failures. Register a devm cleanup action so the reserved memory assignment is released consistently, matching newer Mediatek AFE drivers.
