The issue is in drivers/usb/host/fsl-mph-dr-of.c which copies the
resources to a child platform device. Can you try the following
change:

diff --git a/drivers/usb/host/fsl-mph-dr-of.c 

b/drivers/usb/host/fsl-mph-dr-of.c

Hi Rob,

Thanks a lot for your patch! :-)

First attempt with the latest git kernel:

patching file a/drivers/usb/host/fsl-mph-dr-of.c
Hunk #1 FAILED at 80.
Hunk #2 FAILED at 106.
2 out of 2 hunks FAILED -- saving rejects to file 
a/drivers/usb/host/fsl-mph-dr-of.c.rej

I created a new patch with your modifications. (see attachment)

Unfortunately I can't test it. The git kernel doesn't compile currently.

powerpc-linux-gnu-ld: net/rds/tcp_stats.o:(.bss+0x0): multiple 
definition of `____cacheline_aligned'; init/version.o:(.bss+0x0): first 
defined here

...

make: *** [Makefile:1160: vmlinux] Error 1

@All
Could you please check the multiple definition of `____cacheline_aligned'?
