This triggers an \"already\ndisabled\" WARN() in the first case and leaks an enable reference in\nthe second, leaving the clock ungateable.\n\nGuard both sides with the existing mclk_flag, as fsl_sai.c does with\nmclk_streams.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
