[PATCH net-next 01/10] rxrpc: remove redundant variables 'sp' and 'did_discard'

From: David Howells
Date: Wed Aug 01 2018 - 08:58:55 EST


From: YueHaibing <yuehaibing@xxxxxxxxxx>

Variables 'sp' and 'did_discard' are being assigned,
but are never used, hence they are redundant and can be removed.

fix following warning:

net/rxrpc/call_event.c:165:25: warning: variable 'sp' set but not used [-Wunused-but-set-variable]
net/rxrpc/conn_client.c:1054:7: warning: variable 'did_discard' set but not used [-Wunused-but-set-variable]
