ASoC: dapm: Use struct_size() in krealloc()
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 foo {
int stuff;
struct boo entry[];
};
instance = krealloc(instance, sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, use the new
struct_size() helper:
instance = krealloc(instance, struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.
