Hi -- I'm afraid this pullreq generates a new clang sanitizer warning
running 'make check':
/home/petmay01/linaro/qemu-for-merges/hw/core/loader.c:67:15: runtime
error: null pointer passed as argument 1, which is declared to never
be null
It looks like we try to call open(NULL, ...).
Affected tests are in check-qtest-i386:
tests/bios-tables-test
/i386/acpi/piix4/ipmi
/i386/acpi/q35/ipmi
tests/ipmi-kcs-test
Here's a backtrace:

It looks like the device doesn't handle not having its fru.filename
property set -- this should either cause an error in realize or the
rest of the device code should handle NULL.
