Subject: [PATCH] lib: linear_ranges: Add missing MODULE_LICENSE()

When linear_ranges is compiled as module we get warning
about missing MODULE_LICENSE(). Fix it by adding
MODULE_LICENSE("GPL") as is suggested by SPDX and EXPORTs.

I saw Mark applied the linear-ranges patch. So I sent this fix as
incremental patch - but I still use the same Linus tree as a base of
this fix - the linear-ranges file should be unchanged in regulator tree.
If this does not apply I can clone regulator tree and create this fix on
it.

I don't know if this is the correct way to fix this as the linear-ranges
should be merged to power-supply tree.

I guess we can either:
- Use this patch to fix regulator tree and create fixed tag for
  power-supply(?)
- Add this fix in the original series and resend whole series(?)
- re-create the series and drop the already applied patches. Add this
  fix as a fixup patch in new series and apply it to power-supply tree
  after the linear-ranges from regulator is merged to power-supply.

 Please adviece me if this patch is not the way to go.

Oh, and I am really sorry for the trouble. I saw I had regulators=y
in all of my compilations due to some pincontrol dependencies. So
linear-ranges was not built as module in any of my test compilations :(

Thanks for testing Mark!
