Why was this applied? It replaces one warning with another (that is
actually visible during a normal kernel build):

$ make -j$(nproc) -s allyesconfig drivers/soundwire/intel_init.o
drivers/soundwire/intel_init.c:193:14: warning: ‘sdw_intel_init’ defined
but not used [-Wunused-function]
 static void *sdw_intel_init(acpi_handle *parent_handle,
               ^~~~~~~~~~~~~~

Cheers,
