From 0f89ffefa4e122e7e9bc1c2d716c6052b4601b76 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 4 Jan 2018 12:20:18 +0300 Subject: mfd: lpc_ich: Do not touch SPI-NOR write protection bit on Apollo Lake Just to be on the safe side, don't touch the bit. If write access to the flash chip is needed, the BIOS needs to enable it explicitly.
