[PATCH 004/141] drm/amdgpu: Fix fall-through warnings for Clang

From: Gustavo A. R. Silva
Date: Fri Nov 20 2020 - 13:26:53 EST


In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding multiple break statements instead of just
letting the code fall through to the next case.
