[PATCH] I2C: sensor chip driver refactoring
This patch is a refactoring of some common code among all sensors chip
drivers (except asb100, which was written this way to begin with.)
It saves a handful of lines and ~100-300 bytes per module. It compiles
ok. I've only tested it against one of the drivers, but the changes are
similar across the board and quite mechanical. Please apply.
