[ Upstream commit dc7fe518b0493faa0af0568d6d8c2a33c00f58d0 ]
Attempt to use check_shl_overflow() with inputs of unsigned type
produces the following compilation warnings.
drivers/infiniband/hw/mlx5/qp.c: In function _set_user_rq_size_:
./include/linux/overflow.h:230:6: warning: comparison of unsigned
expression >= 0 is always true [-Wtype-limits]
_s >= 0 && _s < 8 * sizeof(*d) ? _s : 0; \
