From 21031d531eb33a6ad0251ff661a539802700c6e5 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 14 Jun 2017 09:33:06 +0200 Subject: [PATCH] ASoC: intel: bxt: Constify hw_constraints snd_pcm_hw_constraint_list(), *_ratnums() and *_ratdens() receive the const pointers. Constify the corresponding static objects for better hardening.
