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. Signed-off-by: Max Dmitrichenko <dmitrmax@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
