Subject: [PATCH] ALSA: usb: Constify snd_pcm_hardware definitions
Git-commit: 2ead9d087fe2eafecf801dd2ab83bdb66dc08ced
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
Most of snd_pcm_hardware definitions are just copied to another object
as-is, hence we can define them as const for further optimization.
There should be no functional changes by this patch.
