Verified on Intel WCL-U RVP (alpha) mm# 99D5XW.
** Description changed:
+ [SRU Justification]
+
+ [ Impact ]
+
+ No firmware for Intel VPU on Intel Panther Lake platforms.

+
+ Proposed fix in upstream commit c360f595d977 ("intel_vpu: Add firmware
+ for 50xx NPUs and update older ones").
+
+ [ Test Plan ]
+
+ 1. Install linux-firmware from -proposed pocket.
+
+ 2. Check dmesg for kernel driver firmware loading.
