I added the original "SMO8840" entry since I did not have any
docs I just copied the "SMO8A90" entry. Looking at the driver
the only difference seems to be that the LNG2DM only has 8 bits
accuracy where as the LIS2DH12 has 12 bits. I can confirm that
this patch works on my Lenovo Ideapad Miix 320, for which the
original patch was submitted, and that I indeed get 12 bits of
accuracy with this patch.

So this patch is:

Applied to the fixes-togreg branch of iio.git with fixes
and stable tags added.

Whilst it isn't vital this gets backported, it seems unlikely
to do any harm.

Thanks,
