Nit: Titles with or without ':', as long as it's consistent.

There are very few comments in the driver and _this_ is where it was
felt appropriate to do so? If you put "MT6397_INT_STATUS0 + reg * 2"
directly into the call, the line will speak for itself.
Nit: There are also some whitespace issues going on.
