Subject: [PATCH v2 2/4] iio: light: isl29018: Assing ddata to NULL
When iio_get_acpi_device_name_and_data() fails, the ddata may be left
uninitialised. Initialise it to NULL.
Reported-by: Dan Carpenter <dan.carpenter@...aro.org>
Closes: https://lore.kernel.org/r/54fac4a7-b601-40ce-8c00-d94807f5e214@stanley.mountain
Fixes: 14686836fb69 ("iio: light: isl29018: Replace a variant of iio_get_acpi_device_name_and_data()")
