From ba09f5d84e3e39ffb6768e5473073cfb96ba32e3 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 5 Jan 2020 15:47:44 +0100 Subject: [PATCH] ALSA: cs46xx: More constifications Apply const prefix to each possible place: the static tables for registers and op codes, etc. Just for minor optimization and no functional changes.
