Subject: ALSA: atmel: Constify snd_ac97_bus_ops definitions
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=3a3fac8b3b99614d2e4df6b244a313eb5b2716a3;p=linux.git

ALSA: atmel: Constify snd_ac97_bus_ops definitions

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.
