[PATCH 5.14 187/849] coresight: cti: Correct the parameter for pm_runtime_put

[Greg Kroah-Hartman]

From: Tao Zhang <quic_taozha@xxxxxxxxxxx>

commit 692c9a499b286ea478f41b23a91fe3873b9e1326 upstream.

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.
