From 78243ff0a4ec42c1523dc3511b29c5e87936d911 Mon Sep 17 00:00:00 2001 From: Manikanta Maddireddy Date: Thu, 11 Jan 2018 11:38:03 +0530 Subject: [PATCH] PCI: tegra: Use bus->sysdata to store and get host private data Tegra host driver is using pci_find_host_bridge() to get private data; this can be easily avoided by using bus->sysdata to store and get private data removing the pci_find_host_bridge() dependency.
