Subject: [PATCH] ALSA: aoa: Constify snd_kcontrol_new items
Git-commit: dde5199c988b16426cf9a4e0df4b7ae06790471e
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
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.
