Subject: ALSA: pcm: constify function local and read-only table
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b46fe5d9607c2a14618c746a02892ead0f0f4637;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ALSA: pcm: constify function local and read-only table

In a function snd_pcm_hw_params_choose(), target parameters are arranged
into a table. Though each entry of this table is read-only, they don't
have const qualifier.

This commit adds the qualifier.
