This patch doesn't change any hysteresis values, it adds them. As
commented on v2, the sentence about the hysteresis doesn't add any
value IMO, just remove it, or at least explain in a reply why you
think it is valuable.

The node name should use dashes as separator, not underscores, i.e. it
should be 'cpu-crit'. Applicable to all critical trip points.
