you don't need to modify the common code.
my intention was not to change the common code, too, unless other
drivers also need this constraint.
just add the constraint in open callback, such like
int your_pcm_open(snd_pcm_substream_t *substream)
{
...
err = snd_pcm_hw_constraint_minmax(runtime, SNDRV_PCM_HW_PARAM_PERIOD_SIZE,
your_period_size_min, your_period_size_max);
...
}
this is the cleanest solution.
ciao,
Takashi
