Documentation/process/deprecated.rst recommends against performing dynamic size calculations in the arguments of memory allocator functions due to the risk of overflow. Such calculations can wrap around and result in a smaller allocation than expected. Replace the size calculation in cfiq allocation with struct_size() helper to make the code clearer and handle overflows correctly.
