patch "usb: chipidea: msm: Ensure proper controller reset using role switch" added to usb-linus

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

usb: chipidea: msm: Ensure proper controller reset using role switch

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: chipidea: msm: Ensure proper controller reset using role switch
API

Currently we check to make sure there is no error state on the extcon handle for VBUS when writing to the HS_PHY_GENCONFIG_2 register. When using the USB role-switch API we still need to write to this register absent an extcon handle.

This patch makes the appropriate update to ensure the write happens if role-switching is true.
