From f6212e0ab3ff28d4e2e53a520496a052c241df39 Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Wed, 30 Dec 2020 17:24:27 +0000 Subject: [PATCH] ASoC: wm_adsp: Use snd_ctl_elem_type_t for control types Sparse will complain about trying to convert between values declared as snd_ctl_elem_type_t and other types. This patch converts to consistently use snd_ctl_elem_type_t for control type values. A __force cast is needed in a couple of cases where the control type value is parsed out of a DSP data block.
