efi: Remove unnecessary (and buggy) .memmap initialization from the Xen EFI driver
So the following commit: 884f4f66ffd6 ("efi: Remove global 'memmap' EFI memory map") ... triggered the following build warning on x86 64-bit allyesconfig: drivers/xen/efi.c:290:47: warning: missing braces around initializer [-Wmissing-braces] It's this initialization in drivers/xen/efi.c: static const struct efi efi_xen __initconst = { ... .memmap = NULL, /* Not used under Xen. */ ... which was forgotten about, as .memmap now is an embedded struct: struct efi_memory_map memmap; We can remove this initialization - it's an EFI core internal data structure plus it's not used in the Xen driver anyway.
