This is a note to let you know that I've just added the patch titled

    coresight: cti: Correct the parameter for pm_runtime_put

to my char-misc git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-testing branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will be merged to the char-misc-next branch sometime soon,
after it passes testing, and the merge window is open.

If you have any questions about this process, please let me know.

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.
