From fdd1f6fd328ff2e3723fe2a5c94378ef6f217edc Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jan 2020 09:16:51 +0100 Subject: [PATCH] ALSA: isa: 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.
