Returning an error code from pm_runtime_put() merely means that it has not queued up a work item to check whether or not the device can be suspended and there are many perfectly valid situations in which that can happen, like after writing "on" to the devices' runtime PM "control" attribute in sysfs for one example. It also happens when the kernel is configured with CONFIG_PM unset. Accordingly, update rzt2h_wdt_wdtdcr_init() to simply discard the return value of pm_runtime_put() and return success to the caller after invoking that function. This will facilitate a planned change of the pm_runtime_put() return type to void in the future. Signed-off-by: Rafael J.
