From 9b629ad37f2fa9ceda61e2b18bc53f69833235c1 Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Mon, 2 Nov 2020 12:13:23 +0100 Subject: sb/intel/lynxpoint: Correct read width in RMW cycle The register is 32 bits wide, so do not read 16 bits out of it. LynxPoint PCH reference code version 1.9.1 always uses 32-bit accesses.
