According to the BIOS spec, the table contains a n_profile variable indicating how many additional profiles exist in the table. Currently we check that n_profiles is not <= 0. But according to the BIOS spec, 0 is a valid value, and it can't be < 0 anyway because we receive that from ACPI as an unsigned integer.
