This is a note to let you know that I've just added the patch titled
usb: typec: tcpm: update power supply once partner accepts
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.

power_supply_changed needs to be called to notify clients after the partner accepts the requested values for the pps case.
Also, remove the redundant power_supply_changed at the end of the tcpm_reset_port as power_supply_changed is already called right after usb_type is changed.
