Subject: iio: humidity: hdc100x: fix IIO_HUMIDITYRELATIVE channel reporting
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2a0fb9478fdef50a5638bba4a6611222bd51fb6d;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

iio: humidity: hdc100x: fix IIO_HUMIDITYRELATIVE channel reporting

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.
