I tried to only apply the 4 commits of this series, but that would cause build
error as the commit here:
https://lore.kernel.org/all/20210205222644.2357303-2-saravanak@google.com/

so I need to apply the first commit of the "12 commits ending with fb42378dcc7f"
here as well:
https://lore.kernel.org/all/20230207014207.1678715-2-saravanak@google.com/

With the 5 commits applied on the android-mainline branch, the build could boot
to the home screen, but the adb connection could not be created.
For details please check here https://termbin.com/wf9hj.
