[ Upstream commit ebf185efadb71bd5344877be683895b6b18d7edf ]
The driver might skip the ov08x40_identify_module() on probe() based on the acpi_dev_state_d0() check done in probe().
If the ov08x40_identify_module() call is skipped on probe() it should be done on the first stream start. Add the missing call.
Note ov08x40_identify_module() will only do something on its first call, subsequent calls are no-ops.
