If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Arnd Bergmann commit 4f1dd973acffeb67142d39f3bfbc4dd0569f2da6 upstream. 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.
