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.
