[PATCH v6 2/3] soundwire: qcom: constify static struct qcom_swrm_data global variables

From: Srinivasa Rao Mandadapu
Date: Wed Mar 02 2022 - 07:43:40 EST


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.
