From a5a7486e62b0aa4afa1fe1a3b30f7dd682eb1ff8 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Tue, 16 Jul 2019 10:49:04 +0200 Subject: [PATCH] usb, ohci: fix ohci swap register access commit 57faca19a82f ("drivers: USB: OHCI: allow compilation for 64-bit targets") broke ohci support for the mpc85xx based socrates board, as it removed volatile keyword from ohci_readl/writel. Fix this so usb works again on socrates board.
