Subject: [Qemu-devel] [RFC PATCH v2 09/13] alsaaudio: Remove unused error handling of qemu_set_fd_handler
Date: Thu, 14 May 2015 11:34:25 +0800	[thread overview]
Message-ID: <1431574469-9605-10-git-send-email-famz@redhat.com> (raw)
In-Reply-To: <1431574469-9605-1-git-send-email-famz@redhat.com>

The function cannot fail, so the check is superfluous.
