From: Arnd Bergmann Date: Thu, 19 Nov 2015 14:16:30 +0000 (+0100) Subject: sata/mvebu: use #ifdef around suspend/resume code X-Git-Tag: v4.4-rc5~28^2~4 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=4f1dd973acffeb67142d39f3bfbc4dd0569f2da6;p=linux.git 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.
