From 1e1205b7d3e992439b812f59fe0e79bd99b8c79a Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 20 Mar 2018 07:45:42 +0100 Subject: [PATCH] r8169: add helper tp_to_dev In several places struct device is referenced by using &tp->pci_dev->dev. Add helper tp_to_dev() to improve code readability. Signed-off-by: Heiner Kallweit Signed-off-by: David S.
