Subject: serial: amba-pl011: Remove redundant label
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=7f6d942a819cd29854903097392b29010cbcf4da;p=deliverable%2Flinux.git

serial: amba-pl011: Remove redundant label

The label 'out' is only used to return the error code. We can return the
error code directly and remove 'out' label.
