rpmsg: glink: Use struct_size() helper
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 { ... struct intent_pair intents[]; } __packed * msg; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(*msg) + sizeof(struct intent_pair) * count with: struct_size(msg, intents, count) This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A.
