Subject: sata_nv: propagate ata_pci_device_do_resume return value
X-Git-Tag: v2.6.21-rc1~91^2~490
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ce053fa8b532aa038fba6230052daae5cd60eae6;p=platform%2Fkernel%2Flinux-exynos.git

sata_nv: propagate ata_pci_device_do_resume return value

ata_pci_device_do_resume can fail if the PCI device couldn't be re-enabled.
 Update sata_nv to propagate the return value from this call and to not try
to do any other resume activities if it fails.  Fixes a compile warning.
