Subject: [PATCH] ALSA: spi: Constify snd_kcontrol_new items
Git-commit: 1aeb1c7f281ea7b372d5801fda119df73b1be98c
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.
