As of now ueventd only prints the firmware name requested by the uevent, but in case the device has multiple firmware going by the same name it's more interesting to know what file ends up actually being used for the firmware request. Test: m, check logcat Change-Id: Ia90d387f09789d8e8b337a1a178144fad553d37b
