Subject: libata-core.c compile warnings with !CONFIG_PM
Date: Wed, 31 Oct 2007 14:55:28 +0100	[thread overview]
Message-ID: <47288950.3030907@googlemail.com> (raw)

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()
