This is a note to let you know that I've just added the patch titled
iio:imu:bmi160: Fix too large a buffer.
to my staging git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git in the staging-testing branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will be merged to the staging-next branch sometime soon, after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

The comment implies this device has 3 sensor types, but it only has an accelerometer and a gyroscope (both 3D). As such the buffer does not need to be as long as stated.
Note I've separated this from the following patch which fixes the alignment for passing to iio_push_to_buffers_with_timestamp() as they are different issues even if they affect the same line of code.
