 [PATCH v1 08/14] thermal: qcom: Use thermal_zone_get_crit_temp() in
 qpnp_tm_init()

From: Rafael J. Wysocki <rafael.j.wysocki@...el.com>

Modify qpnp_tm_init() to use thermal_zone_get_crit_temp() to get the
critical trip temperature instead of iterating over trip indices and
using thermal_zone_get_trip() to get from a trip index to struct
thermal_trip until it finds the critical one.
