Subject: ALSA: hda/proc - Add const to possible places
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cc75cdfe1d64585d82013632b81199b1e9f1da97;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda/proc - Add const to possible places

Many arrays in hda_proc.c are string arrays that should be covered by
const prefix for increasing the safety and reducing the size.
