Update:
I have added a kset object 'slot' to platform device, with has all the platform device as kobjects with attribute power associated to each of them. So when that power attribute gets modified. I want to remove the device. Something similar to fakephp module. Currently I call
platform_device_unregister(device);
When from the callback when the power attribute is written as 0. That completely frees all the memory allocated for the the device. But what I want to achieve is something similar to.
pci_remove_bus_device((struct pci_dev *)data);
Thanks in advance for any help if possible.
Best regards,
Sougata.

I am new to linux device-drivers. I am trying to fake add, remove sd cards while they are mounted. For systems where sd card controller is connected to PCI bus. I can use fakephp to remove the controller itself. Can similar thing be done with "mmc" bus_type. So that I can fake card addition and removal. The current version of fakephp does not use anything from pci-hotplug subsystem. Is something similar possible ?.
Thank you in advance.
