No out-of-tree is really not important here, and sorry if mentioning
that in my explanation was distracting and caused you to
misunderstand. The issue isn't the crazy wireless driver; the issue is
that suspend on Android happens all the time, and the entire Android
way of using Linux is centered around non-stop suspending, with
triggers to wake up (wifi drivers, for example, like the out-of-tree
qcacld one, but presumably in tree ones too), and ways of controlling
when it goes to sleep (screen blanking, wakelocks, etc). The Android
model of Linux revolves around this, and hence the suspend semantics
for WireGuard respect this model and adjust accordingly, using the
appropriate CONFIG_ANDROID to determine which model we're operating
under. This is not a bandaid, and it doesn't have to do with forks of
the Linux kernel.
