Subject: [PATCH 2/2] ze550kl: Green LED now defaults to on
This helps the user approximately know the moment the kernel is in
control of the hardware, compared to the bootloader.
Practically speaking, this is a sane default for Mobile NixOS and
non-android linux distros, as it shows the device is still on, as long
as there is no userspace LED management software changing the state.
