Subject: staging: usbip: removed unnecessary if-else-statements
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2183b77ece517fe4a17cae59d227d341b9d271c8;p=deliverable%2Flinux.git

staging: usbip: removed unnecessary if-else-statements

In each if-else case "return" is called. This is why
these if-else-statements are useless. Removing them
improves understanding and readability.
