The touchpad on my XPS13 no longer works. It might not be this pull
request, and I'll bisect the exact cause, but this pull seems the most
likely culprit.

Just an early heads-up,

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
bus=pci,vendor=168c,device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520
from ath10k/QCA6174/hw3.0/board-2.bin"

https://bugzilla.kernel.org/show_bug.cgi?id=185621#c9

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:

https://github.com/kvalo/ath10k-firmware/blob/8d15818b0f9c7b09f743538ac2d3e1409779f52a/QCA6174/hw3.0/board-2.bin

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.
