[PATCH 4.9 43/94] acpi, nfit: Fix the memory error check in nfit_handle_mce()

From: Greg Kroah-Hartman
Date: Mon Jun 05 2017 - 13:07:22 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Vishal Verma <vishal.l.verma@xxxxxxxxx>

commit fc08a4703a418a398bbb575ac311d36d110ac786 upstream.

The check for an MCE being a memory error in the NFIT mce handler was
bogus. Use the new mce_is_memory_error() helper to detect the error
properly.
