This causes NULL ptr dereferences (in 5.5 only). It is enough to load
the mac80211_hwsim module.

The backport to 5.5 needs at least these two commits:
commit ac338acf514e7b578fa9e3742ec2c292323b4c1a
Author: Saravana Kannan <saravanak@google.com>
Date:   Fri Feb 21 00:05:09 2020 -0800

    driver core: Add dev_has_sync_state()

commit 77036165d8bcf7c7b2a2df28a601ec2c52bb172d
Author: Saravana Kannan <saravanak@google.com>
Date:   Fri Feb 21 00:05:10 2020 -0800

    driver core: Skip unnecessary work when device doesn't have sync_state()


and playing with includes.

I am not sure if a revert wouldn't be better -- leaving up to maintainers.
