Hello everyone,

Version 3 for adding support for the kx132-1211 accelerometer

KX132 accelerometer is a sensor which:
	- supports G-ranges of (+/-) 2, 4, 8, and 16G
	- can be connected to I2C or SPI
	- has internal HW FIFO buffer
	- supports various ODRs (output data rates)

The KX132 accelerometer is very similair to the KX022A. 
One key difference is number of bits to report the number of data bytes that 
have been stored in the buffer: 8 bits for KX022A vs 10 bits for
KX132-1211.

Changes in v3:
- added two new patches by separating the addition of the 
  i2c_device_id table and the removal of blank lines from other
  unrelated changes
- fixes a warning detected by the kernel test robot
- made all the changes related the chip_info in one patch

Changes in v2:
- added a new patch for warning when the device_id match fails in the
  probe function
- added a new patch for the function that retrieves the number of bytes
  in the buffer
- added a change to the Kconfig file in the patch adding the support
  for the kx132-1211
- various fixes and modifications listed under each patch
