Possible typo in the uapi header?

[YusufKhan-gamedev]

In the DRM uapi header(should be named something like nvidia-drn-ioctl.h) there exists this section:

#define DRM_IOCTL_NVIDIA_GET_DEV_INFO                                      \
    DRM_IOWR((DRM_COMMAND_BASE + DRM_NVIDIA_GET_DEV_INFO),                 \
             struct drm_nvidia_get_dev_info_params)

Is the DRM_IOWR part of it a typo? shouldn't it have been DRM_IOR?
