firewire: move rcode_string() to core
There is nothing audio-specific about the rcode_string() helper, so move it from snd-firewire-lib into firewire-core to allow other code to use it. Signed-off-by: Clemens Ladisch <clemens@ladisch.de> Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> (fixed sound/firewire/cmp.c)
