From 609a70df07af1ff857257fb2e93c3ef281e30710 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Wed, 30 Nov 2016 23:35:47 +0100 Subject: scsi: hpsa: use %phN for short hex dumps Passing one instead of 8 or 16 arguments reduces the size of the generated code somewhat: add/remove: 2/3 grow/shrink: 1/4 up/down: 1772/-2137 (-365) There's one more candidate, unique_id_show, but that uses %02X, and I'm not sure it would be ok to start using lowercase there, so I've left it alone for now.
