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.
