From 462098b090897fbcf00088b225eb7a3adc407e98 Mon Sep 17 00:00:00 2001 From: Levente Kurusa Date: Tue, 29 Oct 2013 20:01:46 +0100 Subject: ata: libata-eh: Remove unnecessary snprintf arithmetic Remove an unnecessary arithmetic operation from a call to snprintf, because the size parameter of snprintf includes the trailing null space. Also, initialize the buffer on definition instead of a memset call.
