From 15480f3ab7a8b5333e170d7168ce8a1012cc735e Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 17 Oct 2016 11:39:32 +0100 Subject: [PATCH] PCI: layerscape: Fix drvdata usage before assignment Commit fefe6733e516 ("PCI: layerscape: Move struct pcie_port setup to probe function") changed the init ordering of the pcie structure, but started to use the pcie->drvdata field before initializing it. Mayhem follows. Fix this by moving the drvdata assignment right before the first use. Tested on LS2085a.
