[PATCH] ALSA: bebob: constify snd_bebob_rate_spec structures

From: Julia Lawall
Date: Sat Oct 10 2015 - 09:50:55 EST


The snd_bebob_rate_spec structure type contains only function pointers. In
all instances of this structure type, the functions are provided statically
and are never changed subsequently. Add a const annotation on all
initializations and uses.

Done with the help of Coccinelle.
