From c98e36fec5c776d022118cdfdd026cdce7053771 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Fri, 22 Feb 2019 01:14:23 +0000 Subject: Revert "src/drivers/intel/wifi: Add a W/A for Intel ThP2 9260" This reverts commit 3afb84a24583f5dee9fb407f11b32253d59392bf. Reason for revert: This is causing issues with the PCIe link and the system is unable to enter S0ix. Until it can be fixed in coreboot revert the change here that is not working properly.
