Fix to return a negative error code from the idr_alloc() error handling case instead of 0, as done elsewhere in this function. Also fix the return value check of idr_alloc() since idr_alloc return negative errors on failure, not zero. Fixes: 2ae0f17d ("genetlink: use idr to track families") Signed-off-by:
