Say yes here to build support for STMicroelectronics accelerometers:

LSM303DLH, LSM303DLHC, LIS3DH, LSM330D, LSM330DL, LSM330DLC,

LIS331DLH, LSM303DL, LSM303DLM, LSM330, LIS2DH12.

LIS331DLH, LSM303DL, LSM303DLM, LSM330, LIS2DH12, H3LIS331DL.
|

This driver can also be built as a module. If so, these modules
|
||||
will be created:
