No, drm_handle_t can be of a different size to void *; converting between integers and pointers of different sizes causes a warning. To eliminate the warning, the value first needs to be passed between uintptr_t and void *, which are of the same size, and then converted to drm_handle_t. The last part is implicit; the drm_handle_t casts are irrelevant/useless. Matthew
