Subject: [PATCH] cifs: style: replace one-element array with flexible-array 

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].

    deprecated.html#zero-length-and-one-element-arrays
