FHCI fails to build in 2.6.33-rc5

[Josh Boyer]

When trying to build the Fedora devel kernel, I get the build error
below.  The *_frame_Q members of the fhci endpoint structure are
indeed declared as 'struct kfifo' and not pointers to such.  The
NULL checks in the fhci_ep0_free function seem odd when you take
that into account.

Thoughts on a fix?  If it's not fixed soon, I'll have to disable
it in the .config.
