Subject: hw/rtc/m48t59-isa: QOM'ify IRQ number
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e89d9fa385c040135a2bce94588dbbd2f7e8e55f;p=qmiga%2Fqemu.git

hw/rtc/m48t59-isa: QOM'ify IRQ number

Exposing the IRQ number as a QOM property not only allows it to be
configurable but also to be printed by standard QOM mechanisms. This allows
isabus_dev_print() to be retired eventually.
