// to 1.0.29. The snd_pcm_sw_params_set_tstamp_type() and
// snd_pcm_sw_params_get_tstamp_type() functions are missing from those versions
// and we need them for the alsa crate which in turn is a dependency of the
// midir crate. The functions are not actually used so we provide dummy
// implementations that return an error. This file can be safely removed when
// the Linux sysroot will be updated to Debian 9 (or higher)
