Gustavo A. R. Silva c56967d674 mei: hdcp: Replace one-element array with flexible-array member
There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

Also, make use of the array_size() helper instead of the open-coded
version in memcpy(). These sorts of multiplication factors need to
be wrapped in array_size().

And while there, use the preferred form for passing a size of a struct.
The alternative form where struct name is spelled out hurts readability
and introduces an opportunity for a bug when the pointer variable type is
changed but the corresponding sizeof that is passed as argument is not.
