From 6fddce26f84c8229db1f6689b6046aa3dff5c887 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 5 Jan 2020 15:47:29 +0100 Subject: ALSA: emu10k1: More constifications Apply const prefix to the remaining possible places: the static tables for init verbs and registers, the string arrays, the conversion tables, etc. Just for minor optimization and no functional changes.
