Having the wifi-breaking error mentioned in the subject with Qualcomm Atheros
QCA6174 802.11ac Wireless Network Adapter [168c:003e] (rev 32) (in a Samsung
Galaxy Book if that's relevant).
dmesg output:

With the following patch (suggested on this list in 2017 by Ryan Hsu), the wifi
works.

After patching I still have the "failed to load pre-cal-pci.../cal-pci..."
errors and the "unsupported HTC service id: 1536" warning, but wifi works.
Is there any reason this patch was never merged in to the ath10k kernel module?
It'd be nice to not have to manually rebuild it every kernel update.
Cheers,
