From: Stefan Raspl <raspl@linux.ibm.com> mainline inclusion from mainline-v6.0-rc1 commit 0a2f4f9893c83bd722bd55a903fb682da2eb24ba category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/IC914B Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- Reworked signature of the function to retrieve the system EID: No plausible reason to use a double pointer. And neither to pass in the device as an argument, as this identifier is by definition per system, not per device. Plus some minor consistency edits.
