The ioctl encoding for this parameter is a long but the documentation says
it should be an int and the kernel drivers expect it to be an int. If the
fuse driver treats this as a long it might end up scribbling over the stack
of a userspace process that only allocated enough space for an int.
This was previously discussed in [1] and a patch for fuse was proposed in
[2]. From what I can tell the patch in [2] was nacked in favor of adding
new, "fixed" ioctls and using those from userspace. However there is still
no "fixed" version of these ioctls and the fact is that it's sometimes
infeasible to change all userspace to use the new one.
Handling the ioctls specially in the fuse driver seems like the most
pragmatic way for fuse servers to support them without causing crashes in
userspace applications that call them.

With the support of generic PM callbacks, drivers no longer need to use
legacy .suspend() and .resume() in which they had to maintain PCI states
changes and device's power state themselves. The required operations are
done by PCI core.
PCI drivers are not expected to invoke PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(),

Earlier, drivers had to manage the device's power states, and related
operations, themselves. With the generic approach, these are done by PCI
core.
The only driver-specific jobs, .suspend() and .resume() doing were invoking
PCI helper functions pci_save/restore_state() and
pci_set_power_state(). This is not recommeneded as PCI core takes care of
that. Hence they became empty-body functions, thus define them NULL.
