Nothing exciting here, patches created mechanically
(common after soft freeze).

qcrypto_cipher_aes_ecb_encrypt expects a 'AES_KEY *' parameter, but
'&aesctx->enc, is a 'const AES_KEY *'. The cast is needed to discard
the const-ness.

Oh I didn't notice. I'll see if I can patch typecast.cocci to avoid this
noise.

This line of code is odd even without the cast. XenPCIPassthroughState*
is a QOM object (TYPE_XEN_PT_DEVICE) which is a subclass of TYPE_PCI_DEVICE,
so the standard way to get the PCIDevice pointer for s would be
  PCIDevice *d = PCI_DEVICE(s);
