From ecc8a0cdca18df5c9a7e84ab29160259123f3ae5 Mon Sep 17 00:00:00 2001 From: Venu Byravarasu Date: Fri, 10 Aug 2012 11:42:43 +0530 Subject: usb: host: tegra: fix warning messages in ehci_remove Existing implementation of tegra_ehci_remove() calls usb_put_hcd(hcd) first and then iounmap(hcd->regs). usb_put_hcd() implementation calls hcd_release() which frees up memory allocated for hcd. As iounmap is trying to unmap hcd->regs, after hcd getting freed up, warning messages were observed during unload of USB. Hence fixing it.
