Thanks for testing!

I noticed blog post about using Librem 5 torch. Unfortunately, it used
very strange/non-standard interface, first using LED as a GPIO to
enable LED controller, then direct i2c access. That is not acceptable
interface for mainline, and it would be better not to advertise such
code, as it will likely become broken in future.
