Subject: [PATCH 2/5] net: tlan: don't set unused function argument

We get a warning for tlan_handle_tx_eoc when building with "make W=1"

drivers/net/ethernet/ti/tlan.c: In function 'tlan_handle_tx_eoc':
drivers/net/ethernet/ti/tlan.c:1647:59: error: parameter 'host_int' set but not used [-Werror=unused-but-set-parameter]
 static u32 tlan_handle_tx_eoc(struct net_device *dev, u16 host_int)

This is harmless, but removing the unused assignment lets us avoid
the warning with no downside.
