[ Upstream commit 4fe81669df50889ff1072c030c59df5f1fa6534e ]
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.
