Subject: [PATCH] ath10k: fix build errors with !CONFIG_PM
 | 
						|
 | 
						|
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'")
