Here is the patch. It makes the w83781d (mis)detection more verbose so
as to help debugging problems. The extra messages of course only show
when I2C chip debugging is enabled. It additionally features some code
refactoring, some CodingStyle cleanups and adds a missing white space in
one debug message.
