From 4c45d24a759d8e7257347ef7200f1319db6ab5f8 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Tue, 12 Dec 2017 07:41:02 +0100 Subject: [PATCH] r8169: switch to device-managed functions in probe Simplify probe error path and remove callback by using device-managed functions. rtl_disable_msi isn't needed any longer because the release callback of pcim_enable_device does this implicitely.
