From b2c0805f77ff6b87bb18994ce70352fecc3ce7fc Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 6 Jan 2009 10:02:38 -0800 Subject: [PATCH] sparc: make proces_ver_nack a bit more readable Impact: clean up The code in process_ver_nack is a little obfuscated. This change makes it a bit more readable by humans. It removes the complex if statement and replaces it with a cleaner flow of control.
