Any kernel changes should be done for all projects if possible

[nahun]

Added change to add to all projects.

I'll understand if this change isn't wanted, but looks like it has been tested before with LibreELEC. Thanks!

but looks like it has been tested before with LibreELEC

That simply means it was added to the default RPi config which isn't used by OpenELEC/LibreELEC, so never actually tested (but should be safe).
