Silva" <gustavoars@...nel.org> To: Alex Deucher <alexander.deucher@....com>, Christian König <christian.koenig@....com>, David Airlie <airlied@...ux.ie>, Daniel Vetter <daniel@...ll.ch> Cc: amd-gfx@...ts.freedesktop.org, dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org, "Gustavo A. R. Silva" <gustavoars@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH][next] amd/amdgpu_ctx: Use struct_size() helper and kmalloc() Make use of the new struct_size() helper instead of the offsetof() idiom. Also, use kmalloc() instead of kcalloc(). Signed-off-by: Gustavo A. R.
