Analyze and fix the following issue in the Linux kernel code: acpi: nfit: fix narrowing conversion in acpi_nfit_ctl
Problem Details: Syzkaller has reported a warning in to_nfit_bus_uuid(): "only secondary bus families can be translated". This warning is emited if the argument is equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() first verifies that a user-provided value call_pkg->nd_family of type u64 is not equal to 0. ...
