patch "serial: st-asc: Potential error pointer dereference" added to tty-linus

[<gregkh@linuxfoundation.org>]

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

    serial: st-asc: Potential error pointer dereference

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-linus 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 hopefully also be merged in Linus's tree for the
next -rc kernel release.

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

Subject: serial: st-asc: Potential error pointer dereference

It looks like we intended to return an error code here, because we
dereference "ascport->pinctrl" on the next lines.
