Subject: [PATCH 3.5 46/96] iio:adc:ad7887 Fix channel reported endianness from cpu to big endian

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

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

From: Jonathan Cameron <jic23@...nel.org>

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.
