From: Tao Zhang quic_taozha@quicinc.com Date: Thu, 19 Aug 2021 17:29:37 +0800 Subject: coresight: cti: Correct the parameter for pm_runtime_put

The input parameter of the function pm_runtime_put should be the same in the function cti_enable_hw and cti_disable_hw. The correct parameter to use here should be dev->parent.
