sata/mvebu: use #ifdef around suspend/resume code
The newly added suspend/resume implementation for ahci_mvebu causes a link error when CONFIG_PM_SLEEP is disabled: ERROR: "ahci_platform_suspend_host" [drivers/ata/ahci_mvebu.ko] undefined! ERROR: "ahci_platform_resume_host" [drivers/ata/ahci_mvebu.ko] undefined! This adds the same #ifdef here that exists in the ahci_platform driver which defines the above functions. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Fixes: d6ecf1581488 ("ata: ahci_mvebu: add suspend/resume support") Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Tejun Heo <tj@kernel.org>
