It will be pushed if I get no objections before 11/29/18. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. If the code is different (ie: not only metadata diffs), due for example to a change in context or macro names, please double check it. Thanks. Kevin Traynor --- >>From 6d96dcc744945a4a90fdacf431ae45300755b3eb Mon Sep 17 00:00:00 2001 From: Alejandro Lucero Date: Thu, 25 Oct 2018 11:49:28 +0100 Subject: [PATCH] bus/pci: compare kernel driver instead of interrupt handler [ upstream commit 630deed612ca382f48a3ef4b65dfc74b7cd09cf9 ] Invoking the right pci read/write functions is based on interrupt handler type. However, this is not configured for secondary processes precluding to use those functions. This patch fixes the issue using the driver name the device is bound to instead.
