[PATCH 4/5] net/9p: Adjust a jump target in p9_client_attach()
From: SF Markus Elfring
Date: Tue Aug 15 2017 - 08:02:42 EST
From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 15 Aug 2017 11:17:23 +0200
Adjust jump labels so that the function implementation becomes smaller.
Delete an extra variable assignment and a check (at the end of
this function).
