Hmm, this triggers:

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

$ gcc --version
gcc (GCC) 10.2.1 20201016 (Red Hat 10.2.1-6)

I'll need to circle back to this later.
