Bruce Fields" , Trond Myklebust , "David S. Miller" , Mika Westerberg , linux-kernel@vger.kernel.org Subject: [PATCH 1/2] svcrpc: fix compile warning about unused variable 'buf' Date: Tue, 15 Jan 2013 09:43:06 +0200 Message-Id: <1358235787-17292-1-git-send-email-mika.westerberg@linux.intel.com> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Sender: linux-nfs-owner@vger.kernel.org List-ID: Commit 7032a3dd923 (svcrpc: demote some printks to a dprintk) changed the printk to a dprintk() macro. Since the macro is not always available we get following compile warning: net/sunrpc/svc.c: In function ‘svc_printk’: net/sunrpc/svc.c:1050:8: warning: unused variable ‘buf’ [-Wunused-variable] Fix this by marking the 'buf' with __maybe_unused. In addition make checkpatch.pl happy by removing space before tab after 'char'.
