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

    serial: ifx6x60: add missed pm_runtime_disable

to my tty git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-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 tty-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: serial: ifx6x60: add missed pm_runtime_disable

The driver forgets to call pm_runtime_disable in remove.
Add the missed calls to fix it.
