It was just testing this patch series(461fc1caed55), to see if it would 
fix my charging issue 
(https://bugzilla.kernel.org/show_bug.cgi?id=201307), which it didn't.

I did however notice that my laptop (ASUS Zenbook UX430UNR/i7-8550U) 
won't wake when opening the lid or pressing a key, the only way to wake 
the laptop is pressing the power button.

I also tested mainline (5.3.0-rc4 b7e7c85dc7b0) and 5.2.8 and the laptop 
wakes without issue when the lid is opened or a key is presed.
