From 7c15430822e71e90203d87e6d0cfe83fa058b0dc Mon Sep 17 00:00:00 2001 From: Len Brown Date: Wed, 1 Feb 2023 12:32:01 -0600 Subject: [PATCH] wifi: ath11k: allow system suspend to survive ath11k 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 Cc: stable@vger.kernel.org Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20230201183201.14431-1-len.brown@intel.com --- 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 @@ -998,7 +998,7 @@ static __maybe_unused int ath11k_pci_pm_ if (ret) ath11k_warn(ab, "failed to resume core: %d\n", ret); - return ret; + return 0; } static SIMPLE_DEV_PM_OPS(ath11k_pci_pm_ops,
