From 861b99216fa64113b113dda98e9db08412cd7bc8 Mon Sep 17 00:00:00 2001 From: Ahmad Fatoum Date: Fri, 14 Apr 2023 16:52:57 +0200 Subject: net: rtl8169: pass physical device for DMA API It shouldn't matter for now, but DMA API should always be called for the physical device, i.e. the struct device underlying the struct pci_device. This the Ethernet device interface parent, so use that instead.
