From ba27816cd8167c64652406d86ca78bcc5989f20f Mon Sep 17 00:00:00 2001 From: Dimitris Michailidis Date: Tue, 14 Dec 2010 21:36:50 +0000 Subject: [PATCH] cxgb4: correct formatting of MSI-X interrupt names The last byte of the buffer for MSI-X names could not be used due to a bogus -1. Also do not explicitly clear the last byte, snprintf will do the right thing. Signed-off-by: Dimitris Michailidis Signed-off-by: David S.
