Subject: x86: ptrace, bts: fix an unreachable statement
X-Git-Url: http://pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=5a8ac9d28dae5330c70562c7d7785f5104059c17;p=linux-2.6-omap-h63xx.git

x86: ptrace, bts: fix an unreachable statement

Commit c2724775ce57c98b8af9694857b941dc61056516 put a statement
after return, which makes that statement unreachable.

Move that statement before return.
