From: Zhang Rui <rui.zhang@intel.com> mainline inclusion from mainline-v5.3-rc1 commit aadf7b38337108627b014fb285147aacdfafe42e category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I47H3V CVE: NA -------------------------------- commit aadf7b38337108627b014fb285147aacdfafe42e upstream. Simplify how the code to discover a package is called. Rename find_package_by_id() to rapl_find_package_domain() Syntax only, no functional or semantic change.
