 [RESEND][PATCH v1 4/5] thermal: imx: Drop critical trip check from
 imx_set_trip_temp()

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

Because the IMX thermal driver does not flag its critical trip as
writable, imx_set_trip_temp() will never be invoked for it and so the
critical trip check can be dropped from there.
