[PATCH v2] ASoC: amd: ps: Fix missing leading zeros in subsystem_device SSID log

From: Simon Trimmer

Date: Tue Mar 31 2026 - 09:27:00 EST


Ensure that subsystem_device is printed with leading zeros when combined
with subsystem_vendor to form the SSID. Without this, devices with upper
bits unset may appear to have an incorrect SSID in the debug output.
