From ebf185efadb71bd5344877be683895b6b18d7edf Mon Sep 17 00:00:00 2001 From: Hans de Goede hdegoede@redhat.com Date: Fri, 20 Dec 2024 15:41:28 +0100 Subject: [PATCH] media: ov08x40: Add missing ov08x40_identify_module() call on stream-start
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.
