Instead of blindly adding newlines to silence checkpatch.pl, what
about reworking the code?
printf("%s\n", ..) cries for a puts().

This printf stuff looks odd. synth_printf() seems to take a format
string, in this case the format string
is returned by spk_msg_get(), smells like a format string bug.

Same here. Also please resolve the ?: mess.

This makro is ugly in many ways.
Why can't this be an static inline function without a dependency on
global state?
