[PATCH 0/6][next] ath6kl: wmi: Replace one-element arrays with flexible-array members

[Gustavo A. R. Silva]

This series aims to replace one-element arrays with flexible-array
members in multiple structures in drivers/net/wireless/ath/ath6kl/wmi.h

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].

This helps with the ongoing efforts to globally enable -Warray-bounds
and get us closer to being able to tighten the FORTIFY_SOURCE routines
on memcpy().

These issues were found with the help of Coccinelle and audited and fixed,
manually.
