The move to a dedicated pwm_backlight_initial_power_state function in
commit 7613c922315e308a6486d802abed2eb74443dffd modified the condition
to set the enable gpio as output. This breaks specific use cases using
that GPIO, such as tegra124-based nyan Chromebooks where backlight
stopped working.
This puts the condition back to the way it was before the move.

Does "[PATCH v2] backlight: pwm_bl: Fix GPIO out for unimplemented
.get_direction()"
(https://lkml.org/lkml/2017/4/4/225) fix your issue?
This definitely solves the issue!
Since this fixes broken backlight (that, in turn, makes systems unusable),
perhaps this should be included in the next rc cycle?
You mean v4.11 final, as there probably won't be another rc?
Yes!
I'm all for it!
Thanks for keeping our attention on this. I sent a PR yesterday (and
hope my GPG key has attracted enough signatures).
Daniel.
