Subject: ALSA: bt87x: Constify hw_constraints
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=934cd5b76d6fb5bbdefd37815a2b9441eb09d02f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: bt87x: Constify hw_constraints

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