patch "usb: typec: tcpm: Keep other events when receiving FRS and" added to usb-linus

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

    usb: typec: tcpm: Keep other events when receiving FRS and

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-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: usb: typec: tcpm: Keep other events when receiving FRS and
 Sourcing_vbus events

When receiving FRS and Sourcing_Vbus events from low-level drivers, keep
other events which come a bit earlier so that they will not be ignored
in the event handler.
