The memory allocation failure checking for in and out is currently
checking if the pointers are valid rather than the contents of what
they point to. Hence the null check on failed memory allocations is
incorrect. Fix this by adding the missing indirection in the check.

If protected virtualization is active on s390, the virtio queues are
not accessible to the host, unless VIRTIO_F_IOMMU_PLATFORM has been
negotiated. Use ccw_transport_features() to fail feature negociation
and consequently probe if that's not the case, preventing a host
error on access attempt.

Hi all,
In another series I proposed to add an architecture specific
callback to fail feature negociation on architecture need.
In VIRTIO, we already have an entry to reject the features on the
transport basis.
Transport is not architecture so I send a separate series in which
we fail the featur

What bothers me here is that arch code depends on virtio now.
It works even with a modular virtio when functions are inline,
but it seems fragile: e.g. it breaks virtio as an out of tree module,
since layout of struct virtio_device can change
