Subject: [PATCH] soundwire: stream: add 'slave' prefix for port range checks
Git-commit: 4bbd6d55a6789e99e74df96cb87a4ed29bbf7f7f
Patch-mainline: v5.18-rc1
References: jsc#PED-850

We can only check for Slave port ranges, the ports are not defined at
the Master level. Also move the function to the 'slave port' block.
