Subject: [PATCH] hw/ide/ahci: Convert AHCIState::ports to unsigned
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
AHCIState::ports should be unsigned. Besides, we never
check it for negative value. It is unlikely it was ever
used with more than INT32_MAX ports, so it is safe to
convert it to unsigned.
