Hi Backports Project Team,

Thank you for providing the project. Me and my team are trying to use Backports to \
install ath11k on our system but we have met some problems.

We have successfully built the Backports Project and installed modules on our system. \
When I boot up the system, it reports some issues like:

[    3.815040] ath11k_pci 0000:06:00.0: BAR 0: assigned [mem 0xb3200000-0xb33fffff \
64bit] [    3.815094] ath11k_pci 0000:06:00.0: enabling device (0000 -> 0002)
[    3.815314] ath11k_pci 0000:06:00.0: qcn9074 hw1.0
[    3.815316] ath11k_pci 0000:06:00.0: failed to register to mhi bus, err = -22
[    3.815352] ath11k_pci 0000:06:00.0: failed to register mhi: -22
[    3.815459] ath11k_pci: probe of 0000:06:00.0 failed with error -22

I have checked the code, and found it was because the driver could not get Length of \
the MHI MMIO region. 

So I checked the version of those modules, and I found packages like mhi.ko having a \
version of 5.15, which was built from backports, like pic 1 in the attachment.

And for packages like ath.ko and ns.ko, they have a version of the kernel version, \
like pic 2 in the attachment.

We are using SLES 15 SP4 with kernel version of 5.14.21-150400.22-default, and \
backports-5.15.58-1. 

If you need more information, please contact me and I will reply the email as soon as \
possible.

Thank you!

Best,
