drm/radeon: Fix fall-through warnings for Clang
In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple warnings by explicitly adding multiple fallthrough pseudo-keyword macros, as replacement for /* fall through */ comments. Notice that Clang doesn't recognize /* fall through */ comments as implicit fall-through markings. Link: https://github.com/KSPP/linux/issues/115 Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
