Subject: rapidio: Replace zero-length array with flexible-array
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a611d137bfe79098471cd22fbf969fa859074921;p=linux.git

rapidio: Replace zero-length 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].
