From 50deb8ac61705b98c89c98db711b64f48d9f9f49 Mon Sep 17 00:00:00 2001 From: Serge Semin Date: Fri, 24 Jun 2022 17:39:38 +0300 Subject: [PATCH] PCI: intel-gw: Drop manual DW PCIe controller version setup Since the DW PCIe common code (dw_pcie_version_detect()) now reads the IP core version directly from the hardware, there is no point manually setting the version for controllers newer than v4.70a. Remove the now-superfluous intel-gw code that sets struct dw_pcie.version.
