The reference\nis leaked and the controller can no longer runtime-suspend, so its clock\nstays enabled.\n\nSwitch to pm_runtime_resume_and_get(), which only increments the usage\ncounter on success.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/25c08be2a5e7715f19a6e02bbe9b0e5f01c77aac","tags":[]},{"url":"https://git.kernel.org/stable/c/58a417a19d80141fff3abe6004e2e47285506e73","tags":[]},{"url":"https://git.kernel.org/stable/c/60a76cdd92e25f576dc58d756a565760dde1f7a1","tags":[]},{"url":"https://git.kernel.org/stable/c/6e05f1c614a57a5d4c364dd12e20c6fd012f9d3e","tags":[]},{"url":"https://git.kernel.org/stable/c/6e20dabffbcd7b222d8e7bb85a7d8e8325df7699","tags":[]},{"url":"https://git.kernel.org/stable/c/a3e9b7f7c9558f8c9592f8f817557bff98707bb3","tags":[]},{"url":"https://git.kernel.org/stable/c/e380fba02908b809f5bbef371259003cf5887bb4","tags":[]},{"url":"https://git.kernel.org/stable/c/e9438ab5328a177c9c0e5df87eb92a7162841e98","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
