From: Stefan Richter Date: Mon, 14 Jun 2010 23:22:45 +0000 (+0200) Subject: firewire: core: remove unused variable X-Git-Tag: firefly_0821_release~9833^2~499^2~8^3~31 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=ae86e81e434072be28ff4e9c1be3cc2562be8749;p=firefly-linux-kernel-4.4.55.git firewire: core: remove unused variable which caused gcc 4.6 to warn about variable 'destination' set but not used. Since the hardware ensures that we receive only response packets with proper destination node ID (in a given bus generation), we have no use for destination here in the core as well as in upper layers. (This is different with request packets. There we pass destination node ID to upper layers because they may for example need to check whether this was an unicast or broadcast request.)
