+	- My tm6010 devices sometimes insist on stop working. I need to turn them off, removing
+	  from my machine and wait for a while for it to work again. I'm starting to think that
+	  it is an overheat issue - is there a workaround that we could do?
+	- Sometimes, tm6010 doesn't read eeprom at the proper time (hardware bug). So, the device
+	  got miss-detected as a "generic" tm6000. This can be really bad if the tuner is the
+	  Low Power one, as it may result on loading the high power firmware, that could damage
+	  the device. Maybe we may read eeprom to double check, when the device is marked as "generic"
+	- Coding Style fixes
+	- sparse cleanups
