Subject: [PATCH 3.16 032/133] iio: pressure: st_pressure: fix drdy
 configuration for LPS22HB and LPS25H

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

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

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

commit ef0bc2e83966b5aed055acb6d16a3788de5205f4 upstream.

Remove int2 configuration parameter for LPS22HB and LPS25H since
these devices export just int1 as data-ready line

Fixes: 931878405b86 (iio:pressure: Add support for LPS25H pressure sensor)
Fixes: e039e2f5b4da (iio:st_pressure:initial lps22hb sensor support)

[bwh: Backported to 3.16:
 - Update the macro used to fill in this field
 - Drop change for LPS22HB]
