QCA 9880 probe failure

[Ben Gamari]

Hello everyone,

I recently purchased a QCA 9880-based PCIe device (Compex WLE900VX 7AA)
and have been having trouble getting ath10k to load. Specifically I see
the following output from the driver on boot,

    ath10k_pci 0000:01:00.0: pci irq msi oper_irq_mode 2 irq_mode 0 reset_mode 0

    ath10k_pci 0000:01:00.0: cannot restart a device that hasn't been started

I see this both with 4.12 and 4.13-rc5 kernels using the latest firmware
in Debian 9 (10.2.4.70).

I have attached the output from devcoredump. Any ideas what might be
going wrong here?

Cheers,

- Ben
