Subject: [PATCH v3 0/4] iio: initialise ddata for iio_get_acpi_device_name_and_data()

Dan reported that ddata might be used uninitialised in some cases.
Let's initialise it to NULL (patches 1 - 3). With that, update one driver
to drop an unneeded anymore check (included in patch 3).

While at it, one more cleanup to kxcjk-1013 (patch 4) is added.

Jonathan, dunno if you want to rebase at this stage (probably not),
but if you do, feel free to fold the patches 1-3 to the initial code.

In v3:
- made Subject more specific for patches 1-3 (Markus)

In v2:
- rewritten patches 1-3 to do the job on the caller side (Jonathan)

Andy Shevchenko (4):
  iio: light: isl29018: Assign NULL to ddata in isl29018_probe()
  iio: light: ltr501: Assign NULL to ddata in ltr501_probe()
  iio: accel: kxcjk-1013: Assign NULL to ddata in kxcjk1013_probe()
  iio: accel: kxcjk-1013: Deduplicate ODR startup time array
