The connect function prints an unintialized error code after an earlier initialization was removed: drivers/net/xen-netback/xenbus.c: In function 'connect': drivers/net/xen-netback/xenbus.c:938:3: error: 'err' may be used uninitialized in this function [-Werror=maybe-uninitialized] This prints it as -EINVAL instead, which seems to be the most appropriate error code. Before the patch that caused the warning, this would print a positive number returned by vsscanf() instead, which is also wrong. We probably don't need a backport though, as fixing the warning here should be sufficient.
