   2 commit 180b65df7ba1e700e28aabfbddbad84b7beebe4b

   5 Subject: fix warning in fs/dlm/netlink.c
   6
   7     this warning:
   8
   9       fs/dlm/netlink.c: In function ‘dlm_timeout_warn’:
  10       fs/dlm/netlink.c:131: warning: ‘send_skb’ may be used uninitialized in this function
  11
  12     triggers because GCC does not recognize the (correct) error flow
  13     between prepare_data() and send_skb.
  14
  15     Annotate it.
