Subject: [PATCH] ALSA: usb: Constify snd_device_ops definitions
Git-commit: c0a142e21bbaeddc9e0ed00045e0ac6c841f1769
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
Now we may declare const for snd_device_ops definitions, so let's do
it for optimization.
There should be no functional changes by this patch.
