Subject: iio:adc:ad7887 Fix channel reported endianness from cpu to big endian
From: Jonathan Cameron <[email protected]>
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.
