Subject: [PATCH] mei: hw: Replace zero-length array with flexible-array member
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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 membersâ€[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].
