From 679bd9508a30b2a0a1baecc9a21dd6c7d8d8d7dc Mon Sep 17 00:00:00 2001
From: Logan Gunthorpe <logang@deltatee.com>

Subject: [PATCH 32/61] DDF: Cleanup validate_geometry_ddf_container()
Patch-mainline: mdadm-4.2+
References: jsc#PED-1009

Move the function up so that the function declaration is not necessary
and remove the unused arguments to the function.

No functional changes are intended but will help with a bug fix in the
next patch.
