First set of IIO fixes for the 4.11 cycle. Regression fixes from 4.10.

These are fixes that came in just to late for the 4.10 cycle.

Two drivers made an accidental assumption of structure arrangement for
struct iio_dev that are no longer true.  It was a typo in the first place
that happened to work until some elements were added to the structure.

* mpl115
  - don't rely on structure field ordering.

iio: pressure: mpl115: do not rely on structure field ordering

Fixes a regression triggered by a change in the layout of
struct iio_chan_spec, but the real bug is in the driver which assumed
a specific structure layout in the first place. Hint: the three bits were
not OR:ed together as implied by the indentation prior to this patch,
there was a comma between the first two, which accidentally moved the
..._SCALE and ..._OFFSET bits to the next structure field. That field
was .info_mask_shared_by_type before the _available attributes was added
by commit 51239600074b ("iio:core: add a callback to allow drivers to
provide _available attributes") and .info_mask_separate_available
afterwards, and the regression happened.

info_mask_shared_by_type is actually a better choice than the originally
intended info_mask_separate for the ..._SCALE and ..._OFFSET bits since
a constant is returned from mpl115_read_raw for the scale/offset. Using
info_mask_shared_by_type also preserves the behavior from before the
regression and is therefore less likely to cause other interesting side
effects.

The above mentioned regression causes unintended sysfs attibutes to
show up that are not backed by code, in turn causing a NULL pointer
defererence to happen on access.

staging: gdm724x: fix a couple array overflows

The find_dev_index() function is frustrating.  If you give it an invalid
index then it returns 0.  That was the intent except there is an
off-by-one so it can return MAX_NIC_TYPE which is one higher than we
want.

There is one caller which had a sanity check to catch invalid returns,
but the other two callers assumed that index was valid.

My feeling is that when we are given invalid indexes, that should be
treated like an error and we abandon what we were doing.
