Subject: [PATCH 3.12 044/235] ssb: Fix error routine when fallback SPROM fails

From: Larry Finger <Larry.Finger@...inger.net>

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

===============

commit 8052d7245b6089992343c80b38b14dbbd8354651 upstream.

When there is a CRC error in the SPROM read from the device, the code
attempts to handle a fallback SPROM. When this also fails, the driver
returns zero rather than an error code.
