Subject: [PATCH] soundwire: qcom: constify static struct qcom_swrm_data global variables
Git-commit: 35732a0694cd2e8642d90f9b49a99742faadd869
Patch-mainline: v5.18-rc1
References: jsc#PED-850

The qcom_swrm_data structures is only required for setting soundwire
params, so make the qcom_swrm_data structure const to allow the compiler
to put it in read-only memory and avoid unintentional modifications.
