Thanks for your patch, which I have applied, with one small change (see
below).

But out of curiosity, could you explain what LPAC is useful for? I
tried to read a bit on the topic, but it's quite confusing. In what
situation is LPAC needed, on embedded Linux devices?

The library license is LGPL-2.1+, so I fixed that up.

Thanks!

Thomas

You need this tool to manage eSIM profiles. See these blog posts [1],
[2] for details.
