[PATCH 4.11 083/150] iio: light: ltr501 Fix interchanged als/ps register field

From: Greg Kroah-Hartman
Date: Mon Jun 12 2017 - 11:30:10 EST


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

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

From: Franziska Naepelt <franziska.naepelt@xxxxxxx>

commit 7cc3bff4efe6164a0c8163331c8aa55454799f42 upstream.

The register mapping for the IIO driver for the Liteon Light and Proximity
sensor LTR501 interrupt mode is interchanged (ALS/PS).
There is a register called INTERRUPT register (address 0x8F)
Bit 0 represents PS measurement trigger.
Bit 1 represents ALS measurement trigger.
This two bit fields are interchanged within the driver.
see datasheet page 24:
