[PATCH] ath10k: move pci suspend/resume functions

[PATCH] ath10k: move pci suspend/resume functions

[Arnd Bergmann]

The combination of two patches has led to a build failure:

drivers/net/wireless/ath/ath10k/pci.c: In function 'ath10k_pci_pm_suspend':
drivers/net/wireless/ath/ath10k/pci.c:3416:8: error: implicit declaration of function 'ath10k_pci_suspend'; did you mean 'ath10k_pci_pm_suspend'? [-Werror=implicit-function-declaration]
drivers/net/wireless/ath/ath10k/pci.c: In function 'ath10k_pci_pm_resume':
drivers/net/wireless/ath/ath10k/pci.c:3428:8: error: implicit declaration of function 'ath10k_pci_resume'; did you mean 'ath10k_pci_pm_resume'? [-Werror=implicit-function-declaration]

This moves the functions outside of the now incorrect #ifdef.

Fixes: 96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but disabled")
Fixes: 6af1de2e4ec4 ("ath10k: mark PM functions as __maybe_unused")

Brian has already fixed this, please check that:

https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/commit/?h=ath-next&id=20665a9076d48e9abd9a2db13d307f58f7ef6647

But apparently I forgot to merge ath-next to wireless-drivers-next, will
do that soon.

Yes, Brian's version is better. I considered the same, but wasn't sure
it was safe.

Yes, it's safe. The code is still basically dead, since the mac80211 ops
get dropped with !CONFIG_PM (so no one calls the
*_hif_{suspend,resume}() functions), but at least we have fewer
#ifdef's.
