Browse source 
* CrOS EC
 - Refactoring of some of cros_ec's headers. include/linux/mfd/cros_ec.h now
   removed, new cros_ec.h added drivers/platform/chrome which contains shared
   operations of cros_ec transport drivers.
 - Response tracing in cros_ec_proto
 
 * Wilco EC
 - Fix unregistration order.
 - Fix keyboard backlight probing on systems without keyboard backlight
 - Minor cleanup (newlines in printks, COMPILE_TEST)
 
 * Misc
 - chromeos_laptop converted to use i2c_new_scanned_device instead of
   i2c_new_probed_device
