drm/radeon: make -fstrict-flex-arrays=3 happy
The driver parses a union where the layout up through the first array is the same, however, the array has different sizes depending on the elements in the union. Be explicit to fix the UBSAN checker. Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3323 Fixes: df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") Acked-by: Christian König <christian.koenig@amd.com> Reviewed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: Kees Cook <keescook@chromium.org>
