From 70dddeee8945a0e62525a278ae7b91778f82f765 Mon Sep 17 00:00:00 2001 From: Octavian Purdila Date: Mon, 2 Mar 2015 21:03:05 +0200 Subject: iio: fix drivers that check buffer->scan_mask If the in-kernel push interface is used we may have a different masks on the device buffer and the kernel buffer and in this case the device should generate data for the reunion of the buffers, which is available at indio_dev->active_scan_mask. Compiled tested only except for bmc150-accel which was tested at runtime with the hardware.

But sampling frequency is actually twice the device bandwidth. This patch fixes this issue.
