RDMA/mlx5: Signedness bug in UVERBS_HANDLER()
The "num_actions" variable needs to be signed for the error handling to work. The maximum number of actions is less than 256 so int type is large enough for that. Fixes: cbfdd442c43e ("IB/uverbs: Add helper to get array size from ptr attribute") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
