Declare snd_pcm_ops structures as const as they are either stored in the
ops field of a snd_pcm_substream structure or passed as an argument to the
function snd_pcm_set_ops. The function argument and the ops field 
are of type const, so snd_pcm_ops structures having this property 
can be made const too.
