[alsa-devel] [PATCH 24/58] ALSA: arm: Constify snd_ac97_bus_ops definitions

Takashi Iwai tiwai at suse.de
Fri Jan 3 09:16:40 CET 2020


Now snd_ac97_bus() takes the const ops pointer, so we can define the
snd_ac97_bus_ops locally as const as well for further optimization.

There should be no functional changes by this patch.
