Subject: thermal: rockchip: fix a impossible condition caused by the warning

From: Caesar Wang <[email protected]>

commit 43b4eb9fe719b107c8e5d49d1edbff0c135a42cb upstream.

As the Dan report the smatch check the thermal driver warning:
drivers/thermal/rockchip_thermal.c:551 rockchip_configure_from_dt()
warn: impossible condition '(thermal->tshut_temp > ((~0 >> 1))) => (s32min-s32max > s32max)'

Although The shut_temp read from DT is u32,the temperature is currently represented as int not long in the thermal driver.
Let's change to make shut_temp instead of the thermal->tshut_temp for the condition.

("thermal: rockchip: consistently use int for temperatures")
