Hi ,
I see this warnings on current git head with !CONFIG_PM :
...
drivers/ata/libata-core.c:768: warning: 'ata_lpm_enable' defined but not used
drivers/ata/libata-core.c:784: warning: 'ata_lpm_disable' defined but not used
...
So far I see ata_lpm_enable() is only used in ata_host_suspend(), ata_lpm_disable() only
in ata_host_resume() which have already #ifdef CONFIG_PM around.
Possible fix is to do the same for ata_lpm_enable() , ata_lpm_disable() and for ata_dev_disable_pm()
which is only used in ata_lpm_enable()
