[PATCH 14/14] drm/amd/pm: Replace one-element array with flexible-array in struct ATOM_Vega10_GFXCLK_Dependency_Table
From: Gustavo A. R. Silva
Date: Wed Oct 07 2020 - 12:05:36 EST
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.
