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

    usb: typec: Add the missed altmode_id_remove() in

to my usb git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-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 usb-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: usb: typec: Add the missed altmode_id_remove() in
 typec_register_altmode()

typec_register_altmode() misses to call altmode_id_remove() in an error
path. Add the missed function call to fix it.
