[ Upstream commit 3b3312f28ee2d9c386602f8521e419cfc69f4823 ]
Return an error from driver probe if the DEVID read from the chip is not one supported by this driver.
In cs35l56_hw_init() there is a check for valid DEVID, but the invalid case was returning the value of ret. At this point in the code ret == 0 so the caller would think that cs35l56_hw_init() was successful.
