[PATCH 4.19 029/125] soundwire: bus: set initial value to port_status

[Greg Kroah-Hartman]

From: Bard Liao <yung-chuan.liao@xxxxxxxxxxxxxxx>

commit f1fac63af678b2fc1044ca71fedf1f2ae8bf7c3b upstream.

port_status[port_num] are assigned for each port_num in some if
conditions. So some of the port_status may not be initialized.
