Description
A flaw was found in the Linux kernel's fsl-edma driver. This vulnerability occurs because the driver attempts to explicitly disable clocks during its removal process, even though these resources are automatically managed. This redundant action can lead to warnings being generated during driver removal, indicating that the clock module is already disabled or unprepared. While not directly exploitable for arbitrary code execution or privilege escalation, these warnings can indicate an unexpected state in the system.
