Say yes here to build support for STMicroelectronics accelerometers:
LSM303DLH, LSM303DLHC, LIS3DH, LSM330D, LSM330DL, LSM330DLC,
LIS331DLH, LSM303DL, LSM303DLM, LSM330, LIS2DH12, H3LIS331DL,
LNG2DM, LIS3DE
LNG2DM, LIS3DE, LIS2DE12
This driver can also be built as a module. If so, these modules
will be created:
