Subject: [PATCH v2 0/2] iio: stk3310: Export near level property for proximity sensor

Userspace tools like iio-sensor-proxy need to be instructed the value from
which they should consider an object is "near". This threshold can be
exported through the sysfs ABI based on the "proximity-near-level"
device-tree property.

This patchset implements this property for the stk3310 driver and adds the
necessary bits to export its value to userspace. It is based on similar
changes applied to the vcnl4000 and ltr501 drivers.

Changes in v2:
  - drop zero-assignment as the variable won't be modified if DT property
    is missing
