[PATCH 6.14 013/311] media: ov08x40: Add missing ov08x40_identify_module() call on stream-start

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@redhat.com>

[ 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.
