Subject: [PATCH net-next 5/5] mlxsw: spectrum_span: Replace zero-length array with flexible-array member

From: Ido Schimmel <idosch@...lanox.com>

In a similar fashion to commit e99f8e7f88b5 ("mlxsw: Replace zero-length
array with flexible-array member"), use a flexible-array member to get a
compiler warning in case the flexible array does not occur last in the
structure.
