First round of fixes for IIO in the 3.13 cycle.

The usual mixed bag of fixes.

* 3 cases where kconfig dependencies were missing.  We need to keep a closer
  eye on this in new drivers.

* hid_sensors was abusing the iio_dev->trigger pointer.  We had a round
  of clearing this out some time ago but this driver clearly slipped through.

* A misuse of the IIO_ST macro, in mcp3422, which we should really make a
  concertive effort to finish removing.

* Avoid a double free introduced by recent buffer reference counting in the
  one driver that (quite reasonably!) does things differently (am335x)

* A missing mutex_unlock in kxsd9 that means that driver has been non
  functional for some time and no one noticed (including me who for once
  actually has one of the supported devices).

* An incorrect assumption about the parameters of sign_extend32 in mcp3422.

So nothing controversial.  The only substantial patch is the hid_sensors
one and that is actually just adding a new pointer to the devices private
state then moving the code over to it.
