[alsa-devel] [PATCH 49/58] ALSA: ice1712: Constify wm-specific tables

Takashi Iwai tiwai at suse.de
Fri Jan 3 09:17:05 CET 2020


The tables defined in wm8766.c and wm8776.c are referred as read-only,
hence they can be declared as const gracefully.

There should be no functional changes by this patch.
