From e1eff7a393d4a4e3ad1cf65fcba899146840bfd2 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Tue, 3 Feb 2009 17:55:19 +0100 Subject: [PATCH] firewire: normalize a variable name Standardize on if (err) handle_error; and if (ret < 0) handle_error; Don't call a variable err if we store values in it which mean success. Also, offset some return statements by a blank line since this how we do it in drivers/firewire.
