From 64543652609fc1a2a816dc38ce4f56eddda9f9a5 Mon Sep 17 00:00:00 2001 From: Max Dmitrichenko Date: Tue, 6 Mar 2007 02:45:01 +0300 Subject: [PATCH] USB: fix Unaligned access in EHCI driver I get following warnings on spar64: Kernel unaligned access at TPC[1000c9e4] ehci_hub_control+0x54c/0x68c [ehci_hcd] Despite of the comment in the patched code, the type cast used there does make unaligned access. The fix was made as it's done in ohci-hub.c.
