During a round of reviewing and testing this morning I found a checkpatch
issue, there are eight spaces which should be replaced by a tab in line 429
of drivers/firmware/efi/libstub/efi-stub-helper.c:

diff --git a/drivers/firmware/efi/libstub/efi-stub-helper.c b/drivers/firmware/efi/libstub/efi-stub-helper.c

 							     image);
 
 	status = efi_call_early(handle_protocol, handle,
-			        &fs_proto, (void **)&io);
+				&fs_proto, (void **)&io);
 	if (status != EFI_SUCCESS) {
 		efi_printk(sys_table_arg, "Failed to handle fs_proto\n");
 		return status;


Also, I noticed that for some reason, efi/urgent commit d7f2e972e702
("efi/x86: remove pointless call to PciIo->Attributes()") is currently
squashed into the top-most commit on the efi/next branch.  Not sure if
intentional, but probably not?

Thanks & have a pleasant weekend.
