[Xen-devel] [PATCH] Event channel request fix

I compiled Xen for SMP and for some strange reason I could not always get the network interface connected to the backend - same for the TPM frontend and probably also block frontend. The attached patch fixes this problem for all three drivers by explicitly setting the requested port for the channel to 0. Since the structure is on the stack (and not declared static) all its members should be explicitly initialized. I don't know why I did not encounter this problem on non-SMP systems before...  [[ Maybe a function requiring all necessary parameters passed to it explicitly as parameters would be a less errro-prone solution?]]
