[PATCH] next: drm/atomic: Use copy_from_user to copy 64 bit data from user space

Copying 64 bit data from user space using get_user is not supported on all architectures, and may result in the following build error. ERROR: "__get_user_bad" [drivers/gpu/drm/drm.ko] undefined! Avoid the problem by using copy_from_user. Fixes: d34f20d6e2f2 ("drm: Atomic modeset ioctl") Cc: Rob
