thermal: underflow bug in imx_set_trip_temp()
We recently changed this from unsigned long to int so it introduced an underflow bug. Fixes: 17e8351a7739 ('thermal: consistently use int for temperatures') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
