From fbc57b2a3e74fd56581bc2acacade9eac22544bd Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 7 Jun 2017 14:23:13 +0200 Subject: [PATCH] ALSA: via82xx: Constify hw_constraints snd_pcm_hw_constraint_list(), *_ratnums() and *_ratdens() receive the const pointers. Constify the corresponding static objects for better hardening.
