[PATCH 3/3] qemu/qemu-plugin: Make qemu_plugin_hwaddr_is_io() hwaddr argument const

[Philippe Mathieu-Daudé]

Rename qemu_plugin_hwaddr_is_io() address argument 'haddr'
similarly to qemu_plugin_hwaddr_device_offset(), and make
it const.

Having the variable named similarly to the 'hwaddr' typedef is
slighly confusing. Also if we declare 'hwaddr' typedef poisoned,
GCC complains qemu_plugin_hwaddr_is_io() use a poisoned variable...
