Two functions were introduced for the purpose of tracing but cause warnings when tracing is disabled:

sound/firewire/motu/amdtp-motu.c:284:13: error: 'copy_message' defined but not used [-Werror=unused-function] static void copy_message(u64 *frames, __be32 *buffer, unsigned int data_blocks, sound/firewire/motu/amdtp-motu.c:271:13: error: 'copy_sph' defined but not used [-Werror=unused-function] static void copy_sph(u32 *frames, __be32 *buffer, unsigned int data_blocks,

Marking them as __maybe_unused will do the right thing here.
