Yes, but a copy of the platform_data is used:

The PCI driver calls ci13xxx_add_device():
http://lxr.free-electrons.com/source/drivers/usb/chipidea/ci13xxx_pci.c#L85

which calls  platform_device_add_data():
http://lxr.free-electrons.com/source/drivers/usb/chipidea/core.c#L364

which makes a copy of the platform_data:
http://lxr.free-electrons.com/source/drivers/base/platform.c#L246
