Subject: [PATCH 11/88] dc395x: uninitialized variable in device_alloc()

3.5.7.8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 208afec4f3be8c51ad6eebe6611dd6d2ad2fa298 upstream.

This bug was introduced back in bitkeeper days in 2003.  We use
"dcb->dev_mode" before it has been initialized.
