Subject: [PATCH 5.3 030/180] iio: humidity: hdc100x: fix IIO_HUMIDITYRELATIVE channel reporting

From: Chris Lesiak <chris.lesiak@...or.com>

commit 342a6928bd5017edbdae376042d8ad6af3d3b943 upstream.

The IIO_HUMIDITYRELATIVE channel was being incorrectly reported back
as percent when it should have been milli percent. This is via an
incorrect scale value being returned to userspace.
