Helper functions like kcalloc or, in this case, devm_kcalloc are preferred. Not only for readability purposes but safety purposes. The changes move `devm_kzalloc(dev, sizeof(var) * n, GFP_KERNEL)` to the helper function `devm_kcalloc(dev, n, sizeof(var), GFP_KERNEL)`. Here is a series of four patches within the Intel/avs drivers that make these changes. They are all compile tested only but should have no effect on runtime behaviour.
