odd msg using kvalo firmware-5.bin w/ KillerAC 1535(QCA6174)

[Michael Scott]

I am currently testing a QCA6174-based M.2/NGFF card (KillerAC 1535) w/ 
linux-next kernel.  When I use the firmware-5.bin from Kalle Valo's 
github: https://github.com/kvalo/ath10k-firmware, I see the following 
message occasionally in dmesg:
ath10k_pci 0000:01:00.0: Unknown eventid: 90118

If I revert back to firmware-4.bin, that message goes away.

(Spoke with kvalo on IRC and passing this info along to the list)
