[PATCH] ACPI: repair nvidia early quirk breakage on x86_64
x86_64 nvidia_bugs() broke when we bailed out on not finding the HPET. However, the quirk works by checking for _not_ finding the HPET... Delete the nvidia_hpet_detected flag and simply test for not finding the HPET, which is simple to do now that acpi_table_parse returns 1 on failure.
