3.13.11-ckt20 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Octavian Purdila <octavian.purdila@xxxxxxxxx>
commit 70dddeee8945a0e62525a278ae7b91778f82f765 upstream.
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.
