From b4e5e70775546480035e156b40040e5d0d4264d1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jan 2020 09:16:53 +0100 Subject: ALSA: pci: Constify snd_kcontrol_new items Most of snd_kcontrol_new definitions are read-only and passed as-is. Let's declare them as const for further optimization. There should be no functional changes by this patch.
