When iio_get_acpi_device_name_and_data() fails, the ddata may be left
uninitialised. Initialise it to NULL and drop unneeded NULL check
in kxcjk1013_probe()

I propose to reduce the scope for this local variable.


How do you think about to use a summary phrase like “Replace a pointer check
by a variable initialisation in kxcjk1013_probe()” instead?
