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].
Use a flexible-array member in struct ATOM_Vega10_GFXCLK_Dependency_Table instead of a one-element array.
