Pull hardening fixes and cleanups from Gustavo A. R. Silva: "Various hardening fixes and cleanups that I've been collecting during the last development cycle: 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)" * tag 'kspp-misc-fixes-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gustavoars/linux: firewire: Remove function callback casts nouveau/svm: Use kvcalloc() instead of kvzalloc() firmware/psci: fix application of sizeof to pointer dmaengine: pxa_dma: Prefer struct_size over open coded arithmetic KVM: PPC: Replace zero-length array with flexible array member aio: Prefer struct_size over open coded arithmetic writeback: prefer struct_size over open coded arithmetic xfs: Use kvcalloc() instead of kvzalloc() assoc_array: Avoid open coded arithmetic in allocator arguments
