    # This is the 2nd commit message:
    framework: update WFD session orientation based on UIBC rotation
    User Input Back Channel (UIBC) support in Wifi Display stack
    allows the sink to send control/commands/preferences to the source
    e.g. touch, keyboard/mouse entry, or orientation/rotation.
    PhoneWindowManager needs to listen for UIBC rotation
    intents and update the preferred rotation when WFD is active.
    Note: HDMI rotation lock overrides WiFi Display UIBC rotation.
