[ Upstream commit f77ebdda0ee652124061c2ac42399bb6c367e729 ]
This is a struct with a trailing zero-length array of icc_node pointers but it's allocated as if it were a single array of icc_nodes instead.
Fortunately this overallocates memory rather then allocating less memory than required.
Fix by replacing devm_kcalloc() with devm_kzalloc() and struct_size() macro.
