PCI / PM: Remove unnecessary error variable from acpi_dev_run_wake()
The result returned by acpi_dev_run_wake() is always either -EINVAL or -ENODEV, while obviously it should return 0 on success. The problem is that the leftover error variable, that's not really used in the function, is initialized with -ENODEV and then returned without modification. To fix this issue remove the error variable from acpi_dev_run_wake() and make the function return 0 on success as appropriate. Signed-off-by: Rafael J.
