[PATCH v3] ALSA: bebob: constify various snd_bebob structures

From: Julia Lawall
Date: Sun Oct 11 2015 - 02:11:02 EST

The structures of type snd_bebob_clock_spec, snd_bebob_rate_spec,
snd_bebob_meter_spec, and snd_bebob_spec are never modified after they are
initialized. Make them all const.

Done with the help of Coccinelle.
