target/linux/mvebu/patches-4.4/000-sata_use_ifdef_around_suspend_resume.patch

   1 The newly added suspend/resume implementation for ahci_mvebu causes
   2 a link error when CONFIG_PM_SUSPEND is disabled:
   3
   4 ERROR: "ahci_platform_suspend_host" [drivers/ata/ahci_mvebu.ko] undefined!
   5 ERROR: "ahci_platform_resume_host" [drivers/ata/ahci_mvebu.ko] undefined!
   6
   7 This adds the same #ifdef here that exists in the ahci_platform driver
   8 which defines the above functions.
