commit 7c15430822e71e90203d87e6d0cfe83fa058b0dc upstream.
When ath11k runs into internal errors upon suspend, it returns an error code to pci_pm_suspend, which aborts the entire system suspend.
The driver should not abort system suspend, but should keep its internal errors to itself, and allow the system to suspend. Otherwise, a user can suspend a laptop by closing the lid and sealing it into a case, assuming that is will suspend, rather than heating up and draining the battery when in transit.
In practice, the ath11k device seems to have plenty of transient errors, and subsequent suspend cycles after this failure often succeed.
