There is a potential execution path in which variable *ret* is checked in an IF statement, and then its value is used to report an error at line 659 without being properly initialized previously:
659 if (ret) 660 dev_err(priv->dev, "Failed to write to 0x%x (%d)\n", reg, ret);
Fix this by initializing variable *ret* to 0 in order to avoid unpredictable or unintended results.

Changes in v2:
- Initialize variable ret to 0 instead of -1. Thanks to Charles Keepax for pointing this out.
- Update subject and commit log.
Patch applied with Charles' ACK.
