Subject: [PATCH] ASoC: wm_adsp: mark more data structures with the const qualifier
Date:   Tue, 11 May 2021 18:14:59 +0100
Message-ID: <20210511171459.270169-1-simont@opensource.cirrus.com>

Precedence: bulk

The callback structures and memory region type table can be marked as
const as they will not change during use.

Fix checkpatch warning against wm_adsp_find_region function by moving
const keyword to form the 'static const struct' pattern.
