Subject: [PATCH] ALSA: timer: Constify snd_timer_hardware definitions
Git-commit: df76996a2c5369769b23a017b6303f7ecacb277b
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
Most of snd_timer_hardware definitions do simply copying to another
struct as-is. Mark them as const for further optimization.
There should be no functional changes by this patch.
