Julia and 0day report:

    Zero-length and one-element arrays are deprecated, see
    Documentation/process/deprecated.rst
    Flexible-array members should be used instead.

However, a straight conversion to flexible arrays yields:

    drivers/acpi/nfit/core.c:2276:4: error: flexible array member in a struct with no named members
    drivers/acpi/nfit/core.c:2287:4: error: flexible array member in a struct with no named members

Instead, just use plain arrays not embedded flexible arrays.
