[PATCH 2/2] USB: OHCI: add a name for the platform-private field
This patch adds an ohci->priv field for private use by OHCI
platform drivers.
Until now none of the platform drivers has used this private space,
but that's about to change in the next patch of this series.

No, we may as well keep it separate like this.

As far as I'm concerned, this doesn't need to be in a patch of its own. It can be merged into the 1/3 patch of the previous series. After all, that patch adds the extra_priv_size field in ohci_driver_overrides, which doesn't make much sense unless there's a way to refer to the private part of the ohci_hcd structure.
