Subject: gigaset: silence GCC warning for unused 'format_ie'
X-Git-Tag: upstream/snapshot3+hdmi~6997^2~143
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6ba6047bf99cf4ade4f63b6b3d97cc3ad763b678;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

gigaset: silence GCC warning for unused 'format_ie'

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.
