use of [1] is deprecated and this usage will potentially break with
upcoming "fortify source" kernel changes
see
<https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays>
when you change to use just [] make sure that any code that uses
sizeof(the current struct) is modified to account for the removal of one
__le32 from the struct
