Mainly some pca954x work, i.e. removal of unused platform data support
and added support for sysfs interface for manipulating/examining the
idle state. And then a mechanical cocci-style patch.
If we use the "i2c-" prefix for the binding documentation file name,
then it should match the file name of the driver, if possible. It is
possible for this driver, so rename it.
