[PATCH 1/4] drm/virtio: Ensure cached capset entries are valid before copying.
From: David Riley <davidriley at chromium.org>
virtio_gpu_get_caps_ioctl could return success with invalid data if a
second caller to the function occurred after the entry was created in
virtio_gpu_cmd_get_capset but prior to the virtio_gpu_cmd_capset_cb
callback being called. This could leak contents of memory as well
since the caps_cache allocation is done without zeroing.
