[Xen-devel] [PATCH] Talk_to_backend on xenbus_probe only if drv->probe was sucessful

[Murillo Bernardes <mfb@xxxxxxxxxx>]

Hi,

This patch makes xenbus_probe only call talk_to_backend if drv->probe() was 
sucessful.

There is no sense in add a watch before drv->probe, because if it fails the 
otherend_changed callback will be called and receive a struct with invalid 
pointers and we get a segfault (ooops).
