Subject: [PATCH net-next] ionic: Remove set but not used variable 'sg_desc'
Date:   Mon, 28 Oct 2019 12:01:21 +0000

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/pensando/ionic/ionic_txrx.c: In function 'ionic_rx_empty':
drivers/net/ethernet/pensando/ionic/ionic_txrx.c:405:28: warning:
 variable 'sg_desc' set but not used [-Wunused-but-set-variable]

It is never used, so can be removed.
