I think it's fair to point out also for Sebastian that Mark spotted a
compile time warning from linear_ranges when it is compiled as a
module. This is only occurring when linear_ranges is compiled as a
module. And that requires CONFIG_REGULATOR to be n and linear_ranges
test to be m. I guess this is unlikely as I think enabling
linear_ranges test code is not common for setups that are not using
linear ranges - but for sure some test setup hits this somewhere.

Problem is that linear_ranges can be compiled as module (it's tristated
in Kconfig) but does not declare MODULE_LICENCE macro.

I sent this incremental patch which should fix the issue:
https://lore.kernel.org/lkml/20200509151519.GA7100@localhost.localdomain/

 - but does applying it to either power-supply or regulator cause a
conflict?

I just wanted to point this out - sorry for the trouble! And please let
me know if you wish me to send some other fix. I will gladly do so and
correct my bugs :)
