From: Joao Martins <joao.m.martins@oracle.com> mainline inclusion from mainline-5.4 commit 472f263660832b90e53bede2020f68cd14f8b76c category: feature bugzilla: https://bugzilla.openeuler.org/show_bug.cgi?id=34 CVE: NA cpuidle-haltpoll can be built as a module to allow optional late load. Given we are setting @owner to THIS_MODULE, cpuidle will attempt to grab a module reference every time a cpuidle_device is registered -- so essentially all online cpus get a reference. This prevents for the module to be unloaded later, which makes the module_exit callback entirely unused. Thus remove the @owner and allow module to be unloaded.
