--------------------------------

[ Upstream commit f765c59c ]

The dp and ufp are defined as bool type, the return value type of
function extcon_get_state should be int, so the type of dp and ufp
are modified to int.

./drivers/phy/rockchip/phy-rockchip-typec.c:827:12-14: WARNING: Unsigned expression compared with zero: dp > 0.
