Subject: Declare all functions static that are not callbacks and not in audio_jack API struct.
X-Git-Tag: 3.3RC0~52^2~29
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9520e891836eaeaed41127a1601980e4a72a0d28;p=thirdparty%2Fshairport-sync.git

Declare all functions static that are not callbacks and not in audio_jack API struct.
If there are any calls from the outside I haven't thought of, that should make them fail.
