Various hardening fixes and cleanups for 5.16-rc1

Hi Linus,

Please, pull the following hardening fixes and cleanups that I've
been collecting during the last development cycle. All of them have
been baking in linux-next.

Fix -Wcast-function-type error:

- firewire: Remove function callback casts (Oscar Carter)

Fix application of sizeof operator:

- firmware/psci: fix application of sizeof to pointer (jing yangyang)

Replace open coded instances with size_t saturating arithmetic helpers:

- assoc_array: Avoid open coded arithmetic in allocator arguments (Len Baker)
- writeback: prefer struct_size over open coded arithmetic (Len Baker)
- aio: Prefer struct_size over open coded arithmetic (Len Baker)
- dmaengine: pxa_dma: Prefer struct_size over open coded arithmetic (Len Baker)

Flexible array transformation:

- KVM: PPC: Replace zero-length array with flexible array member (Len Baker)

Use 2-factor argument multiplication form:

- nouveau/svm: Use kvcalloc() instead of kvzalloc() (Gustavo A. R. Silva)
- xfs: Use kvcalloc() instead of kvzalloc() (Gustavo A. R. Silva)

Thanks
