[PATCH v2] soundwire: intel_init: test link->cdns

intel_link_probe() could return error and dev_get_drvdata() will return null in such case. So we have to test link->cdns after link->cdns = dev_get_drvdata(>auxdev.dev); Otherwise, we will meet the "kernel NULL pointer dereference" error. Signed-off-by: Bard Liao Reviewed-by: Ranjani Sridharan
