Description Hans de Goede 2025-01-23 11:15:13 UTC 
The INT3472 ACPI glue code normally adds a reset GPIO lookup table entry for camera sensors when the INT3472 device provides a type 0x00 aka INT3472_GPIO_TYPE_RESET GPIO.

But the ov7251 driver expects an "enable" pin instead.

A patch to make the INT3472 driver map 0x00 type GPIOs to "enable" instead for ov7521 sensors is pending here:

Reproducible: Always
