If the device is runtime\nsuspended, those clocks may already be disabled.\n\nResume the device before removal, disable runtime PM and drop the\ntemporary runtime PM reference before disabling the clocks.\n\nThis issue was found by manual code inspection.\n\n## Affected\n\n- `Linux >= fb8bd90f83c4dd86bc7fdae406152d63c5852f92 < 605a59639abb9cb63cd7676460461fb0b34756b3`\n- `Linux >= fb8bd90f83c4dd86bc7fdae406152d63c5852f92 < 03244b8713d044425db5dbee08037ecd79b684f9`\n- `Linux >= fb8bd90f83c4dd86bc7fdae406152d63c5852f92 < 3a1caa886d41d9bcc9a402906336eda34a90d323`\n- `Linux >= fb8bd90f83c4dd86bc7fdae406152d63c5852f92 < dbad91a31c482063c0a87c90aa83c9001972c6ac`\n- `Linux >= fb8bd90f83c4dd86bc7fdae406152d63c5852f92 < e1c6c10a6a70a69e29b04fcc1ebe4b9bcbc7a49a`\n- `Linux 4.20`\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":[]}
