Do you get the same mhi error as in the forum post?

qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22

MHI folks, any ideas? I have XPS 13 9310 myself but I'm not able to test
v5.14-rc6 kernel right now.

Hello,

I have hit the same issue on Linux 5.14-rc7:

[ 14.780566] qcom_mhi_qrtr: probe of mhi0_IPCR failed with error -22

This looks to be caused by commit:

ce78ffa3ef16 net: really fix the build...

Reverting this commit results in ath11k being able to load without errors.

Regards,

Yes, I get that same message in my logs.

FWIW, ath11k_pci now does not get loaded on boot. I can manually load
it, but it doesn't seem to do anything.

Do you know if this automatic module loading is related to this qrtr
regression or a separate problem? Can you try Linus' tree and report if
the module load problem still exists? The qrtr regression is fixed now.
