[PATCH 3.10 014/129] iio:adc:ad7887 Fix channel reported endianness from cpu to big endian

From: Greg Kroah-Hartman
Date: Mon Jan 06 2014 - 18:36:48 EST


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

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

From: Jonathan Cameron <jic23@xxxxxxxxxx>

commit e39d99059ad7f75d7ae2d3c59055d3c476cdb0d9 upstream.

Note this also sets the endianness to big endian whereas it would
previously have defaulted to the cpu endian. Hence technically
this is a bug fix on LE platforms.
