If\nthat table is not there, 0 is returned without allocating the acpi_desc\nobject and setting the driver data pointer of the NFIT device.  If the\nplatform firmware triggers an NFIT_NOTIFY_UC_MEMORY_ERROR notification\non the NFIT device at that point, acpi_nfit_uc_error_notify() will\ndereference a NULL pointer.\n\nPrevent that from occurring by adding an acpi_desc check against NULL\nto acpi_nfit_uc_error_notify()."
