#     perf/x86/intel/uncore: Use struct_size() in kzalloc_node()
#     
#     One of the more common cases of allocation size calculations is finding
#     the size of a structure that has a zero-sized array at the end, along
#     with memory for some number of elements for that array. For example:
#     
#     struct intel_uncore_box {
#             ...
#             struct intel_uncore_extra_reg shared_regs[0];
#     };
#     
#     size = sizeof(struct intel_uncore_box) + count * sizeof(struct intel_uncore_extra_reg);
#     instance = kzalloc_node(size, GFP_KERNEL, node);
#     
#     Instead of leaving these open-coded and prone to type mistakes, we can
#     now use the new struct_size() helper:
#     
#     instance = kzalloc_node(struct_size(instance, shared_regs, count), GFP_KERNEL,
#     node);
#     
#     Notice that, in this case, variable size is not necessary, hence it
#     is removed.
#     
#     This code was detected with the help of Coccinelle.
