patch "usb: typec: tcpm: handle SRC_STARTUP state if cc changes" added to usb-linus

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

usb: typec: tcpm: handle SRC_STARTUP state if cc changes

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: handle SRC_STARTUP state if cc changes

TCPM for DRP should do the same action as SRC_ATTACHED when cc changes in SRC_STARTUP state. Otherwise, TCPM will transition to SRC_UNATTACHED state which is not satisfied with the Type-C spec.

Per Type-C spec:
DRP port should move to Unattached.SNK instead of Unattached.SRC if sink removed.
