Subject: ssb: Fix error routine when fallback SPROM fails
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b8425f41346610bd2137eee2c374227ee532e497;p=linux-beck.git

ssb: Fix error routine when fallback SPROM fails

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.
