Yes, resume was successful and I could use wireless network thereafter :)) The ath11k module didn't produce any 
additional log lines after resume, only those "kernel: mhi ..." lines were visible.

> You had Dell XPS 17, right?

Yes, I've got the XPS 17 model with the i9 processor (the i7 and lower are outfitted with the Killer AX1650 wireless card).
