+Subject: drm/i915/gvt: fix memory leak of a cmd_entry struct on error exit
+ path
+
+commit ffdf16edfbbe77f5f5c3c87fe8d7387ecd16241b upstream
+
+The error exit path when a duplicate is found does not kfree and cmd_entry
+struct and hence there is a small memory leak.  Fix this by kfree'ing it.
+
+Detected by CoverityScan, CID#1370198 ("Resource Leak")
+
+Fixes: be1da7070aea ("drm/i915/gvt: vGPU command scanner")
