Subject: [PATCH 3.16 033/133] iio: accel: st_accel: fix data-ready line
 configuration

3.16.51-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Lorenzo Bianconi <lorenzo.bianconi83@...il.com>

commit 4303741f99d617c1fc3c9069195d3d620c2f88c4 upstream.

Remove int2 configuration parameter for LIS3DH, LSM303DLHC, LSM330D,
LSM330DL, LSM330DLC, LSM303AGR, LIS2DH12 and LNG2DM since these devices
export just int1 as data-ready line

Fixes: 23cde4d65cc7 (iio: Added platform data to select the DRDY pin)
Fixes: dcdb0a78cab3 (iio: accel: st_accel: add support to lng2dm)

[bwh: Backported to 3.16:
 - Update the macro used to fill in this field
 - Drop change for LNG2DM]
