While at it, rename the privacy LED's GPIO con_id from "privacy-led" to "privacy" in int3472_get_con_id_and_polarity() and pass it directly to skl_int3472_register_led(), reducing churn when adding new LED types. No functional change.

charset="utf-8" Add support for GPIO type 0x02, which controls an IR flood LED used for face authentication on some laptops (e.g. Dell Pro Max 16 Premium). Without this patch, the kernel logs "GPIO type 0x02 unknown; the sensor may not work" and IR sensors paired with a flood LED cannot function. The flood LED is registered through the LED subsystem like the existing privacy LED. Unlike the privacy LED, it does not have a lookup entry since there is no consumer driver expecting it via led_get(). To support multiple LEDs per INT3472 device, convert the single led struct member to an array with a counter. Signed-off-by: Marco Nenciarini --- The ACPI _DSM tables refer to this GPIO type as "strobe", hence the INT3472_GPIO_TYPE_STROBE define. The userspace-visible LED name uses "ir_flood" instead, as the hardware is an IR flood illuminator, not a flash strobe.
