4.14-stable review patch. If anyone has any objections, please let me know.

From: Brian Norris <briannorris@xxxxxxxxxxxx>
[ Upstream commit 20665a9076d48e9abd9a2db13d307f58f7ef6647 ]
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.
Build tested with the following combinations:
CONFIG_PM=y && CONFIG_PM_SLEEP=y
CONFIG_PM=y && CONFIG_PM_SLEEP=n
CONFIG_PM=n
Fixes: 96378bd2c6cd ("ath10k: fix core PCI suspend when WoWLAN is supported but disabled")
Fixes: 096ad2a15fd8 ("Merge branch 'ath-next'")
