This is blocked by the same implementation details as in #62.

The main reason is that the docs building is using the default.nix "device description" without actually having the full modules system started up, and the current changes breaks documentation generation.

 $ nix-build ./doc/
[...]

Though the change is appropriate, and it looks like it's likely a family-wide issue:

• https://gitlab.com/darkobas/android_device_oneplus_oneplus6/blob/android-8.1/DeviceParts/src/org/omnirom/device/UsbOtgSwitch.java#L31

Though it's not the same /sys/ file. Hmm.

At the very least, I'll be thinking about the appropriate fix for this class of problem, and re-doing this change accordingly. It's also nice that I have the device to test on.
