This can underflow the runtime\nPM usage count and trigger a \"Runtime PM usage count underflow\" warning.\n\nReturn early when the requested state already matches ev_enable_state.\n\n## Affected\n\n- `Linux >= b4b491c0832ef90a7a5070e5975bc8427f2049ca < ad690c0c1b9131725619e352cb7c970488cbf436`\n- `Linux >= b4b491c0832ef90a7a5070e5975bc8427f2049ca < 3365209e758c845a197211645731f0e393a86012`\n- `Linux >= b4b491c0832ef90a7a5070e5975bc8427f2049ca < aa94a37b5a3e560c277dac6f9e5d0d75549a6583`\n- `Linux >= b4b491c0832ef90a7a5070e5975bc8427f2049ca < dd30c10ff60d2b30386c23bb7c61cc97f2385c97`\n- `Linux 3.18`\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":[]}
