Agree.
Currently Balbi's tree has bit old ehci-tegra.c.
Because of this the patches prepared with linux-next need to be rebased onto
this tree and prepare a new patch.
My main intention behind pushing this patch was to get all changes of
ehci-tegra.c from linux-next into balbi's code base so that I can push the same
patch against either balbi's tree or linux-next.
