While talking about XPS13 also a heads-up from me as we have a nasty
regression in ath10k on XPS13 with QCA6174 (though not sure if you have
QCA6174, recent models seem to have that) which completely breaks driver
initialisation an error:

"ath10k_pci 0000:3a:00.0: failed to fetch board data for
from ath10k/QCA6174/hw3.0/board-2.bin"

This is caused by this commit which I believe Dave will be sending to
you soon:

f2593cb1b291 ath10k: Search SMBIOS for OEM board file extension

As a workaround I recommend updating ath10k/QCA6174/hw3.0/board-2.bin
from this link _before_ updating the kernel:

We are working on a fix so that ath10k continues to work with older
board-2.bin, but that might take a day or two still.
