Description
In the Linux kernel, the following vulnerability has been resolved:
ath11k: pci: fix crash on suspend if board file is not found
Mario reported that the kernel was crashing on suspend if ath11k was not able
to find a board file:

The issue here is that board file loading happens after ath11k_pci_probe()
succesfully returns (ath11k initialisation happends asynchronously) and the
suspend handler is still enabled, of course failing as ath11k is not properly
initialised. Fix this by checking ATH11K_FLAG_QMI_FAIL during both suspend and
resume.
