Subject: ALSA: es18xx: Constify hw_constraints
X-Git-Tag: v4.14-rc4~21^2~137
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=21709121fb734715b4c4819aae36aad50cc88fd7;p=platform%2Fkernel%2Flinux-rpi.git

ALSA: es18xx: Constify hw_constraints

snd_pcm_hw_constraint_list(), *_ratnums() and *_ratdens() receive the
const pointers.  Constify the corresponding static objects for better
hardening.
