From 1aeb1c7f281ea7b372d5801fda119df73b1be98c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jan 2020 09:16:56 +0100 Subject: [PATCH] ALSA: spi: 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.
