QCN9274 fails to start firmware (-110) on Linux 6.18/7.0

[Doug Brewer]

Hello,

I'm testing Linux kernel 6.18 and 7.0, and the ath12k driver shows the
following errors:

ath12k_wifi7_pci 0001:11:00.0: BAR 0 [mem 0xf2200000-0xf23fffff 64bit]: assigned

What could be the cause of this issue, and is there any possible
solution? Thank you.
