From 313360b13fd3773eb46811e0f93928d4d58c6f32 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 24 Aug 2018 21:03:14 +0200 Subject: [PATCH] pci: rmobile: Filter out device 1 and 2 Only PCI device 1 and 2 is populated on the R-Car Gen2 internal PCIe controller. Ignore all other devices. This fix prevents a duplication of OHCI controller response on slot 0 and 1.
