Subject: hw/ide/ahci: Convert AHCIState::ports to unsigned
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=44c11b2e69d845e487d0184079899ef15ab626a5;p=qemu.git

hw/ide/ahci: Convert AHCIState::ports to unsigned

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.
