4.12-stable review patch.  If anyone has any objections, please let me know.

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

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

commit add6e6ab3ee0e237822e0951476d3df039b49ec8 upstream.

Set multiread variable to false for LPS22HB pressure sensor since
it is already enabled in CTRL_REG2. Previous configuration does not
cause any issue in I2C communication since SUB Msb has no meaning
whereas it breaks register address in SPI communication

Fixes: e039e2f5b4da (iio:st_pressure:initial lps22hb sensor support)
