From 919c8ede869caeb1a60fb596e759a2bf74030801 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Mon, 16 Nov 2020 18:02:29 +0100 Subject: [PATCH] net: e1000: Use virt_to_phys() instead of pci_virt_to_mem() Using (dm_)pci_virt_to_mem() is incorrect to translate the virtual address in local DRAM to a physical address. The correct macro here is virt_to_phys() so switch to using this macro. As virt_to_bus() is now not used any more, this patch also removes both definitions (DM and non-DM). This issue was detected while testing the e1000 driver on the MIPS Octeon III platform, which needs address translation.
