Subject: SUNRPC: Kill compiler warning when RPC_DEBUG is unset
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b3b536a1230a14e3ef97e5331ba7ad036c6258a9;p=mv-sheeva.git

SUNRPC: Kill compiler warning when RPC_DEBUG is unset

Loads of these:

linux/net/sunrpc/rpcb_clnt.c:942:2: warning: suggest braces around
  empty body in ‘do’ statement [-Wempty-body]

show up when I unset CONFIG_PROC_SYSCTL.  Seen with

  gcc (GCC) 4.6.1 20110908 (Red Hat 4.6.1-9)
