From f729f88a04089d2a0f2783182027347e0446b900 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 5 Jan 2020 15:47:23 +0100 Subject: ALSA: intel8x0: More constifications Apply const prefix to more places: the static tables for PCM definitions, the register tables, etc. Just for minor optimization and no functional changes.
