+Subject: [PATCH] MLK-11340-40 usb: whitelist: update otg & eh's TPL for fsl
+ i.mx
+
+The default TPL is for USB OTG & EH compliance test, the supported
+class is: mass storage, hub, and hid.
+
+Besides, we add one match criterion that matching targeted device
+through class at interface descriptor.
