[PATCH] phy: rockchip-typec: Fix unsigned comparison with less than zero

[Jiapeng Chong]

The dp is defined as bool type, the return value type of function
extcon_get_state should be int, at the same time,if(dp>0) is used as the
conditional statement, so the type of dp is modified to int.

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