Subject: ALSA: es1938: Constify hw_constraints
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=44d715074d4006d30d3eaa35412f2d31896245ad;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: es1938: Constify hw_constraints

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