[ Upstream commit 2db4578ef6ffb2b52115ca0ebf897b60ec559556 ]
If an error occurs after a successful of_get_i2c_adapter_by_node() call, it
should be undone by a corresponding i2c_put_adapter().
Add the missing i2c_put_adapter() call.

When possible use dev_err_probe help to properly deal with the
PROBE_DEFER error, the benefit is that DEFER issue will be logged
in the devices_deferred debugfs file.
And using dev_err_probe() can reduce code size, the error value
gets printed.
