The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=ac2b16d3b11b88ba1f3023de3645575542be4ca3 commit ac2b16d3b11b88ba1f3023de3645575542be4ca3 Author: Jose Luis Duran <jlduran@gmail.com> AuthorDate: 2022-02-23 16:38:58 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2022-02-27 16:13:04 +0000 libefivar: Correct condition check for AcpiExp text format According to UEFI Spec, for ACPI Expanded Device Path, when HIDSTR=empty, CIDSTR=empty, UID STR!=empty, the ACPI Expanded Device Path node can be displayed as AcpiExp(HID,CID,UIDSTR) format. And if UID is 0 and UIDSTR is empty, then use AcpiEx format. This patch is to correct the condition check to follow UEFI Spec when convert the device path node to the AcpiExp text format.
