If CONFIG_PM=n:
drivers/net/usb/lan78xx.c: In function ‘lan78xx_get_stats64’:
drivers/net/usb/lan78xx.c:3274: error: ‘struct dev_pm_info’ has no member named ‘runtime_auto’
If PM is disabled, the runtime_auto flag is not available, but auto
suspend is not enabled anyway. Hence protect the check for runtime_auto
by #ifdef CONFIG_PM to fix this.

Alternatively, we can add a dev_pm_runtime_auto_is_enabled() wrapper to
include/linux/pm.h, which always return false if CONFIG_PM is disabled.
The only other user in non-core code (drivers/usb/core/sysfs.c) has a
big #ifdef CONFIG_PM check around all PM-related code.
Thoughts?
