linux-next: build warning after merge of the cifs tree

[Stephen Rothwell]

Hi all,

After merging the cifs tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from include/linux/seqlock.h:36:0,
                 from include/linux/time.h:6,
                 from include/linux/stat.h:19,
                 from include/linux/module.h:10,
                 from fs/cifs/smbdirect.c:16:
fs/cifs/smbdirect.c: In function 'smbd_recv_buf':
include/linux/spinlock.h:260:3: warning: 'flags' may be used uninitialized in this function [-Wmaybe-uninitialized]
   _raw_spin_unlock_irqrestore(lock, flags); \
   ^
fs/cifs/smbdirect.c:1865:16: note: 'flags' was declared here
  unsigned long flags;
                ^

Introduced by commit

  ac69f66e54ca ("CIFS: SMBD: Implement function to receive data via RDMA receive")

OK, this is a false positive, but annoying.

I am using gcc 5.2.0.
