Subject: [PATCH] ASoC: wm_adsp: Remove the wmfw_add_ctl helper function
Git-commit: 56717d72f7a811799e8d138ff3d49325272c5cf6
Patch-mainline: v5.17-rc1
References: bsc#1203699

The helper function wmfw_add_ctl is only called from one place and that
place is a function with only 2 lines of code. Merge the helper function
into the work function to simplify the code.
