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. https://bugzilla.kernel.org/show_bug.cgi?id=216968 Fixes: d1b0c33850d29 ("ath11k: implement suspend for QCA6390 PCI devices") Signed-off-by: Len Brown <len.brown@xxxxxxxxx> Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Kalle Valo <kvalo@xxxxxxxxxx> Link: https://lore.kernel.org/r/20230201183201.14431-1-len.brown@xxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/net/wireless/ath/ath11k/pci.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/net/wireless/ath/ath11k/pci.c +++ b/drivers/net/wireless/ath/ath11k/pci.c @@ -979,7 +979,7 @@ static __maybe_unused int ath11k_pci_pm_ if (ret) ath11k_warn(ab, "failed to suspend core: %d\n", ret); - return ret; + return 0; } static __maybe_unused int ath11k_pci_pm_resume(struct device *dev) Patches currently in stable-queue which might be from len.brown@xxxxxxxxx are queue-6.2/wifi-ath11k-allow-system-suspend-to-survive-ath11k.patch
