All the use of part_name by the called functions should check if it is NULL before trying to assign anything to *part_name. This change has broken loading boot.cfg via the EFI path "esp:/EFI/NetBSD/boot.cfg" since the call to bios_boot() at https://nxr.netbsd.org/xref/src/sys/arch/i386/stand/efiboot/devopen.c#292 with a non-NULL last argument means devname gets updated and now points to the partition with a root filesystem rather than the EFI system partition. Cheers, Simon.
