As the "q" variable is a pointer to "struct xe_exec_queue" and this structure ends in a flexible array: struct xe_exec_queue { [...] struct xe_lrc lrc[]; }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the argument "size + size * count" in the kzalloc() function. This way, the code is more readable and more safer.
