X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=de900b182ef1826e887c4458d7af0696f08fcc4b;p=linux.git

ALSA: sonicvibes: Constify hw_constraints

snd_pcm_hw_constraint_list(), *_ratnums() and *_ratdens() receive the
const pointers.  Constify the corresponding static objects for better
hardening.
