Commit 7032a3dd9 (svcrpc: demote some printks to a dprintk) adds warnings

[Russell King <rmk@arm.linux.org.uk>]

Bruce,

Your commit below causes a new build warning in the kernel:

net/sunrpc/svc.c: In function 'svc_printk':
net/sunrpc/svc.c:1050:7: warning: unused variable 'buf'

which affects all ARM builds; it is the only warning in a lot of cases.
Please can you resolve this new warning using whatever method you feel
is most appropriate, thanks.

    svcrpc: demote some printks to a dprintk
    
    In general I'd rather random bad behavior on the network won't trigger a
    printk.
