Subject: [Qemu-devel] [PATCH 05/17] target-i386: cpu_x86_init(): move error handling to end of function
Date: Mon, 12 Nov 2012 19:38:50 -0200	[thread overview]
Message-ID: <1352756342-13716-6-git-send-email-ehabkost@redhat.com> (raw)
In-Reply-To: <1352756342-13716-1-git-send-email-ehabkost@redhat.com>

Doing error handling on a single place will make it easier to make sure
memory is freed, and that error information is properly printed or
returned to the caller.
