[PATCH 3.2 114/147] gigaset: silence GCC warning for unused 'format_ie'

[Ben Hutchings]

3.2.95-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Bolle <pebolle@xxxxxxxxxx>

commit 6ba6047bf99cf4ade4f63b6b3d97cc3ad763b678 upstream.

Building Gigaset's CAPI support without Gigaset's debugging enabled
triggers this GCC warning:
    'format_ie' defined but not used [-Wunused-function]

Silence this warning by wrapping format_ie() in an "#ifdef
CONFIG_GIGASET_DEBUG" and "#endif" pair.
