As this an unusual merge problem between two branches I applied this manually to ath.git master-pending branch for now. Let's see if kbuild bot is happy now.

Build errors have been reported with CONFIG_PM=n: drivers/net/wireless/ath/ath10k/pci.c:3416:8: error: implicit declaration of function 'ath10k_pci_suspend' [-Werror=implicit-function-declaration] drivers/net/wireless/ath/ath10k/pci.c:3428:8: error: implicit declaration of function 'ath10k_pci_resume' [-Werror=implicit-function-declaration] These are caused by the combination of the following two commits: 6af1de2e4ec4 ("ath10k: mark PM functions as __maybe_unused") 96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but disabled") Both build fine on their own. But now that ath10k_pci_pm_{suspend,resume}() is compiled unconditionally, we should also compile ath10k_pci_{suspend,resume}() unconditionally. And drop the #ifdef around ath10k_pci_hif_{suspend,resume}() too; they are trivial (empty), so we're not saving much space by compiling them out. And the alternatives would be to sprinkle more __maybe_unused, or spread the #ifdef's further.
