The wakeup list node is initialized before registration,\nso it can be deleted without checking whether the device is wakeup-\ncapable like in the original teardown path.\n\n[ rjw: Rename acpi_device_del_list() to acpi_device_cleanup() ]\n[ rjw: Subject and changelog edits ]","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/0b9053cd0955c7cd66d71a8442be33926d70e197","tags":[]},{"url":"https://git.kernel.org/stable/c/15512c6b5dea72fb5f1f41c1aa96f3f32531ca03","tags":[]},{"url":"https://git.kernel.org/stable/c/83ee65feadc88de681abc6e977d54eceda95abd7","tags":[]},{"url":"https://git.kernel.org/stable/c/8cc2017aa804f157e717b5fd471e50fbddfec654","tags":[]},{"url":"https://git.kernel.org/stable/c/a414485ebc2aa50907d0ce97cde2b1a353696897","tags":[]},{"url":"https://git.kernel.org/stable/c/f30379b8a4e24623594235dd5aefb2957e0cc228","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
