Subject: [PATCH] Net: rxrpc: signed and unsigned issue, need type cast for n_elem.

From: Chen Gang <[email-masked]>
Date: Mon, 22 Apr 2013 18:24:00 +0800

n_elem is unsigned int which never < 0.
  but it seems, we realy need check it whether < 0.
  so need a type cast for it.

  find it by EXTRA_CFLAGS=-W
