SubjectRe: [PATCH] serial/imx: propagate error from of_alias_get_id instead of using -ENODEV
From
2011/12/15 Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:
> A quick look at of_alias_get_id shows that in the error case it returns
> -ENODEV, too, but still it's better style to propagate the value as is.
