From: Hans de Goede <hdegoede@xxxxxxxxxx> media: ov08x40: Add missing ov08x40_identify_module() call on stream-start upstream status: Accepted in media subsystem co-maintainer tree: https://git.linuxtv.org/sailus/media_tree.git/log/drivers/media/i2c/ov08x40.c?h=devel (this tree gets rebased before merging so no git hash) 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.
